Notes

1omegae = 87l.3 Spinks, 1934 from band heads Spinks, 1934.
2Strong perturbations.
3Independent rotational analyses by d'Incan and Femelat, 1967 and Dixit, Krishnamurty, et al., 1970 gave different B values. The values of Femelat and Jones, 1974 are based on plates with higher resolution and are adopted here.
