Notes

1Extended progression (v"=0) converging to 46715 cm-1. The vibrational constants given represent this progression up to v'=17 only.
2Extrapolated from observed phosphorescence spectra in various solid matrices at low temperature Meyer, Jones, et al., 1971. Lifetime in these matrices Meyer, Smith, et al., 1970.
3alphav= -4.4E-8(v+1/2)2 - 2.8E-9(v+1/2)3.
4From the effective Be; 2.012043 Å at the minimum of the Born-Oppenheimer potential curve, see Stieda, Tiemann, et al., 1976.
5IR sp. 8
6Microwave sp. 9
7Thermochemical value (mass-spectrom.) Coppens, Smoes, et al., 1967. The convergence limit in E-X, assuming dissociation into 3P + 3P, gives 5.66 ± 0.13 eV, the error being due to the uncertainty with regard to the particular triplet components involved.
8In low-temperature argon and nitrogen matrices.
