Notes

1The band head analyses by Hayes and Nevin, 1955 and Hayes, 1955 lead to negative values of omegaexe (~ -0.5) Hayes and Nevin, 1955, Hayes, 1955.
2Q,R,S heads; possibly quintet system.
3Strong 0-0 sequence, multiple heads.
4Multiple heads.
5|A| ~ 41.
6Different values for omegaexe suggested by Muller, 1943 and Haynes and Nevin, 1955.
7Thermochemical value (flame photometry) Bulewicz, Phillips, et al., 1961.
