The reaction enthalpy at 298 K relies on an activation energy of 167.4 kJ/mol and assumes a negligible activation barrier for product recombination. The enthalpy of formation relies on -723.9 ± 6.7 kJ/mol for the enthalpy of formation of Fe(CO)5(g). At least two other estimates of the activation energy for the Fe(CO)4(g) + CO(g) recombination have been reported: 7.1 kJ/mol Miller and Grant, 1985 and 16.7 kJ/mol Walsh, 1986. In Lewis, Golden, et al., 1984 authors have considered that the Fe(CO)4(g) fragment is in its singlet excited state.

Notes

1Preceding 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.
2Dissociation produced by absorption in these bands and subsequent atomic fluorescence Lee, Carlson, et al., 1975; predissociation into C+ + O- Locht and Durer, 1975.
3Calcu1ated 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.

6The 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.

9Preionization observed in electro-ionization of CO Carbonneau and Marmet, 1973.
10Absorption and photoionization coefficients from 1000 to 600 Å Cook, Metzger, et al., 1965.
11These 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.
12This strong absorption band is clearly present but not assigned on the spectrogram of Ogawa and Ogawa, 1972.
13An absorption band at this wavenumber is visible but not identified on the published spectrogram of Ogawa and Ogawa, 1972.
14This 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).
15Previously called G [see missing citation]. The present G 1Π is from Ogawa and Ogawa, 1974.

20The 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.

29Rotational lines are diffuse because of predissociation.
30In 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.

33A 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.

37This 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.
38Only 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.

41This 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.
