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