Notes

1Interpretation by Barrow and Yee, 1974.
2Only one band observed; its isotope shift indicates a fairly high value of v'.
3Long extrapolation from high vibrational levels; only v=7,8 of B 0+ [DeltaG(7 1/2) = 196.39] and v=11...15 of A 0+ have been analyzed. The v numbering derives from isotope shifts of levels which are often perturbed.
4x ~geq 1084 according to the interpretation by Barrow and Yee, 1974 of the V shaded UV absorption bands.
5DeltaG(1/2) = 468.04.
6 Barrow, Dudley, et al., 1972 give Be = 0.13220, alphae = 0.000545 which do, however, not reproduce B0 and B1 as determined by them.
7Estimated Drowart and Goldfinger, 1966 by comparison with other molecules of this type.
