Notes
| 1 | Constants from Raziunas, Macur, et al., 1963 who attribute the double heads observed for most bands to isotope splitting; Guernsey, 1934 assumes spin doubling. Guernsey, 1934, Sen, 1937, and Gurvich, Novikov, et al., 1965 give all slight1y different constants. |
| 2 | Thermochemical value (mass-spectrom.) Burns, 1966. For flame photometric results see Gurvich and Veits, 1958, Gurvich, Novikov, et al., 1965. |
