Notes

1From the analysis Gosavi, Greig, et al., 1971 of the absorption spectrum. An earlier analysis Howell, 1944 of absorption measurements by Walter and Barratt, 1929 gave omega' ~ 250 Howell, 1944, omega" ~ 220 Howell, 1944.
2Shading uncertain.
3Unclassified bands from 11800 to 30000 cm-1. 4
4Suggested vibrational constants in Patel and Rajan, 1968.
