Gas Phase Heat Capacity (Shomate Equation)

Cp° = A + B*t + C*t2 + D*t3 + E/t2
H° − H°298.15= A*t + B*t2/2 + C*t3/3 + D*t4/4 − E/t + F − H
S° = A*ln(t) + B*t + C*t2/2 + D*t3/3 − E/(2*t2) + G
    Cp = heat capacity (cal/mol*K)
    H° = standard enthalpy (kcal/mol)
    S° = standard entropy (cal/mol*K)
    t = temperature (K) / 1000.

Henry's Law constant (water solution)

kH(T) = H exp(d(ln(kH))/d(1/T) ((1/T) - 1/(298.15 K)))
H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar))
d(ln(kH))/d(1/T) = Temperature dependence constant (K)

Notes

1 Wight and Brion, 1974 obtain 530.8 eV from the electron energy loss spectrum.
2Strong X-ray absorption peak (excitation 1s0 → 1πg).
3Possible upper state symmetries have been discussed on theoretical Leclercq, 1967 and empirical Lindholm, 1968 grounds. Several of these Rydberg levels have also been observed in the high resolution electron energy loss spectrum Geiger and Schroder, 1968.
4Strongly preionized.
5A weak satellite series approximately 50 cm-1 longward of the main bands has been observed by Codling and Madden, 1965.
6Preionization observed by photoionization mass-spectrometry Dehmer and Chupka, 1975.
7The limits refer to band origins; the approximate head-origin separation has been subtracted from the observed heads.
8Both preionization (to O2+ + e-) and predissociation (to O+ + O- for n≥5) have been established by photoionization mass- spectrometry Dehmer and Chupka, 1975.
9The 0-0, 1-0, 2-0 bands are overlapped. Vibrational numbering confirmed by 18O2 isotope shifts.
10Rotational analyses for v=3,5,7; v=4,6,8,9 are diffuse.
11Probably progression II of Tanaka and Takamine, 1941, extended and reassigned by Katayama, Huffman, Tanaka [unpublished, see Figure 1 of Dehmer and Chupka, 1975].
12Preionization observed by photoionization mass-spectrometry Dehmer and Chupka, 1975. Several autoionizing levels have been studied by photoelectron spectroscopy Bahr, Blake, et al., 1971, Kinsinger and Taylor, 1973, Tanaka and Tanaka, 1973. See also Nicholson, 1963.
13These progressions have been reassigned and extended by Katayana, Huffman, Tanaka (see 11) and include most of the bands of progressions I, N, I', P of Price and Collins, 1935. They occur in the region of the second member (4sσg) of the Rydberg series beginning with H [ Lindholm, 1968, see 15). Other Rydberg series going to a 4Πu or A 2Πu may also be present; higher members possibly account for many unassigned bands in the region 810-740 Å (123000 - 135000 cm-1).
14That the diffuse nature of the bands is at least partly due to predissociation has been shown by the observation of 0-I lines in fluorescence; Carlson, 1974 gives cross sections for this reaction from 850 to 650 Å (117000 - 154000 cm-1).
15Long but strongly perturbed v' progression composed of bands previously Price and Collins, 1935 assigned to four shorter progressions H, H', M, M'; first member (3sσg) of a Rydberg series converging to a 4Πu of O2+ Lindholm, 1968, Edqvist, Lindholm, et al., 1970). The intensity distribution [ Huffman, Larrabee, et al., 1964, Matsunaga and Watanabe, 1967, see also Dehmer and Chupka, 1975] closely resembles that of the a 4Πu progression in the photoelectron spectrum Edqvist, Lindholm, et al., 1970.
16Very complex spectrum 90400 - 90700 cm-1.
17Vibrational numbering uncertain.
18 Ogawa and Yamawaki, 1969 assumed this to be a 3Σu+ state; reassigned by Chang and Ogawa, 1973.
19B1 = 1.698, D1 = 42E-6.
20Partial rotational analyses of a weak and diffuse 0-0 band and of stronger 1-0 and 2-0 bands Chang and Ogawa, 1973.
21The 1802 isotope effect shows that this is a 0-0 band Ogawa, Yamawaki, et al., 1975.
22The two components are assumed to correspond to the ground state splitting (A = 200) of O2+ Yamawaki and Ogawa, 1972, Collins, Husain, et al., 1973.
23Perturbed rotational structure. According to Yamawaki and Ogawa, 1972 these constants refer to the 1-0 band, the unresolved 0-0 band being at 79180 cm-1.
24Constants for Π+; B0-) = 1.611, D0-) = 14E-6. Constants for the diffuse v=1 level were also determined.
25Group of six line-like features similar to F ← X.
26v=1 diffuse
27The 18O2 isotope shift shows that this is a 0-0 band. F 3Πu is a mixed state resulting from the avoided crossing of the unstable 3Πu state (arising from 3P + 3P) with the lowest 3Πu Rydberg state (3pσu); see Buenker and Peyerimhoff, 1975, Buenker, Peyerimhoff, et al., 1976. Oscillator strengths Huebner, Celotta, et al., 1975.
28The three strongest bands in this region at 80369, 82916, 85345 cm-1 [called "longest band", "second band", "third band" by Tanaka, 1952] have long resisted attempts at identification. Recent ab initio calculations Yoshimine, Tanaka, et al., 1976, Buenker, Peyerimhoff, et al., 1976 have shown that very probably they correspond to the second 3Σu- state formed by the avoided crossing of B 3Σu- with the lowest 3Σu- Rydberg state (3pπu). The predicted ωe is of the order of 3000 cm-1. All three bands are diffuse [O(1D) atoms have been detected in the predissociation of E 3Σu- Stone, Lawrence, et al., 1976] and show double peaks (two close double peaks for the "second band"). In 1802 the rotational structure of the "longest band" is resolved [B'= 1.3072 Ogawa, 1975, D'= 1.8E-6 Ogawa, 1975, λ'= 3.37 Ogawa, 1975, γ'= +0.045 Ogawa, 1975] and confirms that the upper state is indeed 3Σu- Ogawa, Yamawaki, et al., 1975. On the basis of the observed isotope shift Ogawa, Yamawaki, et al., 1975 prefer the assignment of the "longest band" as 1-0b. [see also Buenker, Peyerimhoff, et al., 1976]. f values of 0.0102, 0.0080, 0.0015, for three bands have been determined from electron energy loss measurements Huebner, Celotta, et al., 1975.

40From electron energy loss spectra. C and d are considered to be the lowest Rydberg states (3sσg) of O2. Apparent oscillator strengths, summed over the first four bands of the C-X progression, yield an f value of f= 0.00074 Huebner, Celotta, et al., 1975.
41ΔG(3/2) = 1960 Cartwright, Hunt, et al., 1973, Huebner, Celotta, et al., 1975, ΔG(5/2) = 1780 Cartwright, Hunt, et al., 1973, Huebner, Celotta, et al., 1975 [average of values given by Cartwright, Hunt, et al., 1973 and Huebner, Celotta, et al., 1975].
42ωeye = -0.139, γe = -0.000556 from a low order fit to v ≤ 4; the representation of levels having v ≤ 13 requires seven Yi0 and seven Yi1 coefficients Krupenie, 1972, Albritton, Schmeltekopf, et al., 1979; T0 values of Ackerman and Biaume, 1970 (absorption) and Creek and Nicholls, 1975 (emission) agree to better than 0.1 cm-1 [note, however, two typographical errors for G0 and G3 in Table 5 of Creek and Nicholls, 1975]. Convergence limit of the vibrational levels at 57127.5~ cm-1 Brix and Herzberg, 1954. RKR potential Krupenie, 1972, Vanderslice, Mason, et al., 1960, Ginter and Battino, 1965.
43The spin splitting constants at low v are λ = 1.5, -γ ~ 0.04 cm-1. They increase rapidly above v~12 Brix and Herzberg, 1954, Bergeman and Wofsy, 1972.
44Predissociation above v=2 established by line width measurements in absorption Wilkinson and Mulliken, 1957, Carroll, 1959, Hudson and Carter, 1968, Ackerman and Biaume, 1970, Snopko, 1970, Hudson and Mahle, 1972; maximum at v=4, subsidiary peaks at v=7,11. Ab initio calculations Schaefer and Miller, 1971, Julienne and Krauss, 1975, Julienne, 1976 show that the repulsive 5Πu state from normal atoms is the main contributor to the predissociation with smaller contributions from 1Πu, 3Πu [earlier investigators assumed this to be the only contributor Riess and Ben-Aryeh, 1969, Murrell and Taylor, 1969, Child, 1970, Durmaz and Murrell, 1971] and 3Σu+. Evidence for inverse predissociation has been foumd by Myers and Bartle, 1968; see also Wray and Fried, 1971, Sharma and Wray, 1971.
45β =0.22E-6 for low v; Dv increases rapidly above v~4.
46The B state levels have been observed in absorption from v'=0 to the convergence limit (see 42) Brix and Herzberg, 1954, Ackerman and Biaume, 1970. Absorption by vibrationally excited O2(v" ≤ 5) Ogawa, 1966, Ogawa and Chang, 1968; data for 17O16O, 18O16O, 18O2 Halmann, 1964, Halmann and Laulicht, 1965; absorption in inert gas matrices Bass and Broida, 1964, Schnepp and Dressler, 1965, Boursey, Roncin, et al., 1970 and Fugol, Gimpelevich, et al., 1976. The formation of O(1D) atoms by photoabsorption in the adjoining continuum has been verified by Stone, Lawrence, et al., 1976. Emission bands with low v' and high v" are observed in various electrical discharges Feast, 1950, Herman, Herman, et al., 1961, Creek and Nicholls, 1975.
47For intensity measurements in the discrete portion of the B-X system see Bethke, 1959, Blake, Carver, et al., 1966, Farmer, Fabian, et al., 1968, Hudson and Carter, 1968, Ackerman, Biaume, et al., 1970, Hasson, Hebert, et al., 1970, Huebner, Celotta, et al., 1975, and in the continuum Kosinskaya and Startsev, 1965, Blake, Carver, et al., 1966, Goldstein and Mastrup, 1966, Huebner, Celotta, et al., 1975; at the absorption maximum near 1445 Å (69200 cm-1) the absorption coefficient is 382 cm-1 (σ = 1.42E-17 cm2) Goldstein and Mastrup, 1966. Absorption f values vary from 3.4E-10 for the 0-0 band to 3.4E-5 for the 14-0, 15-0 bands to 1.3E-5 for the 20-0 band, yielding an oscillator strength sum of ~32E-5 for the Schumann-Runge bands. The overall electronic absorption oscillator strength is 0.162 which represents an upper limit if, as suggested by Huebner, Celotta, et al., 1975 and recently confirmed by Cartwright, Fiamengo, et al., 1976, the continuum contains contributions from other dissociative states; see also Julienne, Neumann, et al., 1976. A rather different total f value of 0.040 is derived from shock-tube absorption and emission studies Treanor and Wurster, 1960, Krindach, Sobolev, et al., 1963, Buttrey, 1969; the discrepancy is probably due to the r-dependence of the electronic transition moment Marr, 1964, Halmann and Laulicht, 1967, Allison, Dalgarno, et al., 1971, Julienne, Neumann, et al., 1976. Franck-Condon factors based on RKR and similar potentials Jarmain, 1963, Halmann and Laulicht, 1967, Harris, Blackledge, et al., 1969, Krupenie, 1972, Albritton, Schmeltekopf, et al., 1979; Halmann and Laulicht, 1967 give data for 18O2. The spectral emissivity in the Schumann-Runge bands has been discussed by Ben-Aryeh, 1968, Buttrey, 1969. Franck-Condon densities Jarmain and Nicholls, 1964.
48The constants of Herzberg, 1952 have been adjusted Jarmain and Nicholls, 1967, Krupenie, 1972 to the revised vibrational numbering (v' raised by one unit) of Broida and Gaydon, 1954. The spin- splitting constants for low v are λ= -4.95 and γ ~0; they decrease appreciably above v~7. RKR potential Vanderslice, Mason, et al., 1960, Degen, Innanen, et al., 1968, Jarmain, 1972, Krupenie, 1972.
49Dv increases rapidly above v~4.
50The tentative identification of the A → b transition in an oxygen afterglow by Broida and Gaydon, 1954 was not confirmed by Barth and Kaplan, 1957. Other unidentified features in the nightglow and in the oxygen afterglow have been variously attributed to the A → a and A' → a transitions by Wraight, 1976 and Chamberlain, 1958, respectively. A high resolution trace of one of these bands at 4007 Å can be seen in Figure 1 of Degen, 1968.
51First observed in absorption at atmospheric pressure and a path of >25 m Herzberg, 1932, Herzberg, 1952. The bands occur in emission in the nightglow Chamberlain, 1955, Chamberlain, 1958 and in various afterglows Broida and Gaydon, 1954, Barth and Kaplan, 1957, Barth and Patapoff, 1962, Degen and Nicholls, 1968. According to Broida and Peyron, 1960, Bass and Broida, 1964 bands correlated with this system have also been observed in matrix isolation studies; these bands have recently been reassigned, see 57.
52For detailed intensity measurements in the discrete region and in the adjoining continuum see Ditchburn and Young, 1962, Blake, Carver, et al., 1966, Degen and Nicholls, 1969, Ogawa, 1971, Hasson and Nicholls, 1971. The electronic absorption oscillator strength is cross sections ~E-7; Cross sections in the continuum vary from ~0.5E-24 cm2 at 2400 Å to ~30E-24 cm2 at 1920 Å where transitions to other dissociative states begin to make significant contributions to the observed intensity Hasson and Nicholls, 1971. Franck-Condon factors and Franck-Condon densities Jarmain and Nicholls, 1967, Degen, Innanen, et al., 1968, Jarmain, 1972, Krupenie, 1972.
53The separation of the F3 and F2 components in v=6, extrapolated to J=0, is 145.9 cm-1.
54The vibrational constants and v00 have been estimated from measurements of the diffuse high-pressure bands (see 56). The only accurately known vibrational interval is ΔG(11/2) = 611.2 for the F3 component Herzberg, 1953. The vibrational numbering is uncertain.
55Extrapolated from B5 and B6 assuming a linear Bv curve; the v numbering has been estimated (see 54).
56Only two weak bands have been analyzed at low pressure and 800 m path length Herzberg, 1953. At high pressure and in liquid O2 a fairly strong progression of diffuse triplets has been studied by many investigators. This progression appears to be the analogue in (O2)2 of the A' ← X bands (their intensity increases with the square of the pressure) Wulf, 1928, Finkelnburg and Steiner, 1932, Herman, 1939, Herzberg, 1953. For lack of other information the A' ← X 0-0 band is assumed to be at the position of the first diffuse high-pressure band.
57Visible emission bands of oxygen in low temperature matrices Broida and Peyron, 1960 have recently been reinterpreted Richards and Johnson, 1976 as belonging to the A' → X system.
58ωeze ~ +0.00055. The constants refer to the revised vibrational numbering suggested by Degen, 1968; see 60.
59This system was only observed in Xe matrices (v00 = 24552) by excitation with VUV light.
60In absorption the 6-0,... ,11-0 bands [new v' numbering of Degen, 1968, 1-0,... ,6-0 in the old numbering of Herzberg, 1953] have been observed with path lengths of 800 m atm Herzberg, 1953; in emission several bands with low v' are seen in the afterglow of an oxygen-argon mixture Degen and Nicholls, 1966, Degen, 1968. The v'=0 progression is the strongest feature of the Venus night airglow Lawrence, Barth, et al., 1977.
61These constants have been re-evaluated [ Albritton, Harrop, et al., 1973, see also Creek and Nicholls, 1975] from the measurements of the b-X system Babcock and Herzberg, 1948 using improved lower state constants; γe = -0.000042.

In emission in the aurora and nightglow Meinel, 1950 as well as in various discharges Kaplan, 1947, Kvifte, 1951, Herman, Herman, et al., 1961, Noxon, 1961. Band intensities [in cm-1 km-1 atm-1 (STP)] for the 0-0, 1-0, 2-0 bands are 532, 40.8, 1.52, respectively Miller, Boese, et al., 1969; slightly smaller values in Galkin, Zhukova, et al., 1972. The transition probability for the 0-0 band is 0.075 s-1 [average of values given by Miller, Boese, et al., 1969 and Galkin, Zhukova, et al., 1972]. Dianov-Klokov, 1964 gives the band oscillator strengths f00 = 2.5E-10 Dianov-Klokov, 1964, f10 ~0.2E-10 Dianov-Klokov, 1964.

65Pressure induced spectra a ← X, b ← X as well as simultaneous transitions in two colliding molecules have been studied by many investigators. See recent papers by Findlay, 1970, McKellar, Rich, et al., 1972 which refer to earlier work.
