Notes
1 | Preceding the two K limits (see 88) are strong Rydberg series of absorption bands. The longest-wavelength absorptions correspond to excitation to the 2π orbital yielding a weak 3Π ← X 1Σ+ and a strong 1Π ← X 1Σ+ peak at 283 and 285 eV for the transitions from lsC and at 529 and 532 eV for the transitions from 1s0 Nakamura, Morioka, et al., 1971. The transitions to the 1Π states have also been observed in electron impact experiments at 287.7 and 534.4 eV van der Wiel, El-Sherbini, et al., 1970. |
2 | Dissociation produced by absorption in these bands and subsequent atomic fluorescence Lee, Carlson, et al., 1975; predissociation into C+ + O- Locht and Durer, 1975. |
3 | Calcu1ated Franck-Condon factors for ionization: X 2Σ+ ← X 1Σ+, A 2Π ← 1Σ+, and B 2Σ+ ← X 1Σ+, see Krupenie and Benesch, 1968 and Nicholls, 1968. Observed Franck-Condon factors from photoelectron spectrum Turner and May, 1966, Comes and Speier, 1971, Gardner and Samson, 1974; absolute ionization cross-sections Judge and Lee, 1972, Samson and Gardner, 1976. |
4 | Tanaka's diffuse series (joining on to D2, D3) |
5 | Ogawa and Ogawa's series III (joining on to T6) |
6 | The progression P5 of Tanaka, 1942 [called T in MOLSPEC 1 and missing citation] must be reclassified as representing the members n=6, 7, and 9 of series III; see the spectrograms of Tanaka, 1942 and Ogawa and Ogawa, 1972. |
7 | ν = 158664 - R/(n-0.902-0.232/n)2; n = 4,5,...,18. |
8 | Diffuse looking bands. |
9 | Preionization observed in electro-ionization of CO Carbonneau and Marmet, 1973. |
10 | Absorption and photoionization coefficients from 1000 to 600 Å Cook, Metzger, et al., 1965. |
11 | These series and progressions from the high resolution work of Ogawa and Ogawa, 1972 agree only partially with the early work Tanaka, 1942, Takamine, Tanaka, et al., 1943 at lower resolution. |
12 | This strong absorption band is clearly present but not assigned on the spectrogram of Ogawa and Ogawa, 1972. |
13 | An absorption band at this wavenumber is visible but not identified on the published spectrogram of Ogawa and Ogawa, 1972. |
14 | This is the strongest system of Hopfield and Birge, 1927. It is clearly present on the reproduction of Ogawa and Ogawa, 1972, but these authors consider the first band at 950 Å as due to v'=1 of K(4pσ)←X. Do not assign the second (strongest) band at 941 Å and consider the third band at 933 Å as n=5, v'=0 of the Rydberg series which starts with C(3pσ) and E(3pπ). |
15 | Previously called G [see missing citation]. The present G 1Π is from Ogawa and Ogawa, 1974. |
16 | v=0 diffuse by predissociation, v=1 sharp. The rotational constants are for v=1 Ogawa and Ogawa, 1974. |
17 | Jevons, 1932 gives ωe = 2112 Jevons, 1932, ωexe = 198 Jevons, 1932, presumably from private communication by Hopfield-Birge. |
18 | B1 = 1.837, D1 = 3E-6. |
19 | Clear case of accidental predissociation for J=31 (e level) at 94872 cm-1 above v=0, J=0 of X 1Σ+ Simmons and Tilford, 1974. |
20 | The ν00 values for B→A, C→A, E→A are not deperturbed and, therefore, do not add up with the deperturbed ν00 for A-X (see also 53) to the ν00 values listed for B-X, C-X, and E-X. |
21 | Oscillator strength f00 = 0.094 Lassettre and Skerbele, 1971. |
22 | Λ-type doubling, Δν = 0.011N(N+1). Triplet splitting unobservably small as for most Rydberg states. |
23 | H0 = -1.9E-7. The rotational constants represent average values for the two Λ-doubling components. |
24 | Only v=0 and 1 observed in absorption, only v=0 in emission. ωe, ωexe derived with the aid of isotope (12,13CO) data, see Tilford and Vanderslice, 1968. |
25 | μel = 4.5 D Fisher and Dalby, 1976, from Stark effect observations on the Herzberg bands Fisher and Dalby, 1976. |
26 | Lifetime τ(v=0) = 1.5 ns Hesser, 1968, Dotchin and Chupp, 1973; electronic branching ratios Dotchin and Chupp, 1973. |
27 | Kepa, 1969 and Asundi, Dhumwad, et al., 1970 have studied the bands of the isotopic molecules 13C16O and 12C18O. |
28 | Osci1lator strength f00 = 0.163 Lassettre and Skerbele, 1971. |
29 | Rotational lines are diffuse because of predissociation. |
30 | In the electron energy loss spectrum Swanson, Celotta, et al., 1975 find a peak at 90858 cm-1 which, according to them, cannot be identified with the j 3Σ+ state. |
31 | single 0-v" progression. |
32 | Only two vibrational levels observed, ΔG(1/2) = 2082.26. ωe, ωexe derived with the aid of isotope data Tilford and Vanderslice, 1968. |
33 | A partial breaking off of the rotational structure in the Å bands occurs above J=37 in v'=0 and above J=17 in v'=1 leading to a dissociation limit at 89595 ± 30 cm-1 Douglas and Moller, 1955. RKR potential missing citation. μel = 1.60 D Fisher and Dalby, 1976 from Stark effect measurements on the Å bands Fisher and Dalby, 1976. |
34 | Lifetime τ(v=0) = 21.8 ns Imhof, Read, et al., 1972, good agreement with Hesser, 1968, Rogers and Anderson, 1970, Dotchin and Chupp, 1973. τ(v=1) = 15.5 ns Imhof, Read, et al., 1972; Rogers and Anderson, 1970 give 23.8 ns. Electronic branching ratios Dotchin and Chupp, 1973. |
35 | Franck-Condon factors missing citation. Kepa and Rytel, 1970 have studied the rotational structure in the Å bands of the isotopic molecules 12C18O, 13C16O, 13C18O and the perturbations in these isotopes as well as in 12C16O; see also Douglas and Moller, 1955, Janjic, Pesic, et al., 1969. |

37 | This state is strongly perturbed by the higher vibrational levels of the a' 3Σ+ state (near its dissociation limit). Dieke and Mauchly, 1933 derived B0 = 1.89 from lines with N values between 7 and 15. Gero, 1935 from deperturbed term values derived B0 = 2.058 ; Schmid and Gero, 1935, 2 gave α = 0.033 Schmid and Gero, 1935, 2. The listed values of Be and αe are from a revised deperturbation by Stepanov, 1940 who also gives the deperturbed constants ΔG(1/2) = 2188 Stepanov, 1940 and τ0 = 83816 Stepanov, 1940. |
38 | Only two vibrational levels, v=0 and 1, have been observed. Breaking off on account of predissociation in v=0 above N=55, in v=1 above N=42 Gero, 1935, Gero, 1936. The absence of v=2 is puzzling since it is expected to lie below the dissociation limit Barrow, Gratzer, et al., 1956. |

41 | This interpretation was first suggested by Gero, 1938. It is in agreement with the data of Tilford and Simmons, 1972 on the a'-X system. The occurrence of these particular vibrational levels of a' 3Σ+ in the emission spectrum is due to strong interaction with b 3Σ+. Indeed, the levels mentioned were observed as "extra" bands accompanying the b 3Σ+ → a 3Π (third positive) bands. |
