Notes
| 1 | Short progression of resonances in electron transmission. 15 |
| 2 | Energy relative to X 3 g-(v=0) of neutral O2. |
| 3 | Long progression of resonances in electron transmission. 16 |
| 4 | Extrapo1ated energy of v=0 relative to X 3g-(v=0) of neutral O2. |
| 5 | Absorption in KBr, vibrational numbering uncertain Ikezawa and Rolfe, 1973. |
| 6 | Observed in alkali halide crystals at 4.2 and 2 K. |
| 7 | Estimated v00 for the free O2- ion, by extrapolation from data for various host crystals Holzer, Murphy, et al., 1968. |
| 8 | A = -160 cm-1 103. |
| 9 | From electron scattering cross sections for gaseous O2 Boness and Schulz, 1970, Linder and Schmidt, 1971; similar measurements by Gray, Haselton, et al., 1972
suggest e = 1140 Gray, Haselton, et al., 1972, exe = 12 Gray, Haselton, et al., 1972.
A direct measurement of G"(1/2) in the
photodetachment spectrum Celotta, Bennett, et al., 1972 gives G"(1/2) ~ 1090 cm-1 Celotta, Bennett, et al., 1972, in agreement with
extrapolations from Raman frequencies in alkali halide crystals Holzer, Murphy, et al., 1968. Anharmonicities derived
from low-temperature fluorescence spectra (see 6) are approximately 8.7 Ikezawa and Rolfe, 1973. |
| 10 | From a Franck-Condon factor analysis of the photodetachment spectrum Celotta, Bennett, et al., 1972 and a similar evaluation by Parlant and Fiquet-Fayard, 1976 of the electron scattering data of Linder and Schmidt, 1971. |
| 11 | Raman sp. 17 |
| 12 | In alkali halide crystals. |
| 13 | From D00(O2) and the electron affinities of O(1.462 eV) and O2. |
| 14 | From the O2- photodetachment spectrum Celotta, Bennett, et al., 1972; see also Pack and Phelps, 1966, 2. From endothermic negative-ion
charge-transfer reactions Tiernan, Hughes, et al., 1971 obtain I.P.  0.45 ± 0.1 eV. The theoretical value is 0.42eV
Zemke, Das, et al., 1972. |
| 15 | "Band b". Suggested "grandparent" state b 4g- of O2+. |
| 16 | "Band a". The negative ion state results from the addition of two Rydberg electrons in the
3s g orbital to the O2+ core in the a 4u state ("grandparent"). |
| 17 | In alkali ha1ide crystals and in solid KO2 and NaO2. |
