Notes

1ΔG(3/2) = 328.95; see 2.
2B1 = 0.1305, B2 = 0.123. Extensive perturbations by states having Ω = 1 or 2.
3Vibrational numbering confirmed by isotope studies.
4Strong mutual perturbations between B and A as well as other perturbations in B.
5Only v'=3 and 4 have been analyzed, ΔG(7/2) = 310.79.
6Estimated from the magnitude of the Ω-type doubling; see 7.
7Be(F3) - Be(F2) = +0.00063.
8Estimate based on a Birge-Sponer extrapolation of the ground state vibrational levels Ahmed and Barrow, 1974; see also Drowart and Goldfinger, 1966.
