Notes

1Large electronic isotope shift.
2Based on the 1-0 and 2-0 rotation-vibration bands Spanbauer and Rao, 1965; Using the older measurements of Talley, Kaylor, et al., 1950 for v=0,1,2 and their own measurements of the B-X system at high v" Johns and Barrow, 1959 obtain: G(v) = 3001.008(v+1/2) - 47.969(v+1/2)2 + 0.58504(v+1/2)3 - 0.028102(v+1/2)4 + 9.9959E-4(v+1/2)5 - 2.0290E-5(v+1/2)6; (v≤24) Bv = 11.00375 - 0.30362(v+1/2) + 0.0038495(v+1/2)2 - 1.7593E-4(v+1/2)3 + 9.1687E-6(v+1/2)4 - 3.1044E-7(v+1/2)5; also higher terms in the expression for Dv. De Lucia, Helminger, et al., 1971 obtain from the submillimeter microwave spectrum B0= +10.860346.

7From photoelectron spectra Lempka and Price, 1968, Brundle, 1970, 2, Walker, Dehmer, et al., 1973. Photoionization studies yield 16.03 eV Berkowitz, Chupka, et al., 1971.
8Laser emission in the 4-3, 3-2, 2-1, 1-0 bands in transverse discharges through D2 + SF6 Coldhar, Osgood, et al., 1971; in a chemical laser source the emission extends to v=12 and Δv=6 Sileo and Cool, 1976.
9The radiative lifetime of v=1 is 0.032 s; see Hinchen, 1974, missing citation.
