Notes

1A0 = +156.70; slight J dependence.
20-0 sequence only; the R2 + Q21 and Q1 + R12 heads of the 0-0 band are at 16285.8 and 16125.8 cm-1, the corresponding heads of the 1-1 band at 16193.2 and 16035.2.
3Λ-type doubling Δv(2Π1/2) = 0.037(J+1/2). Perturbations.
4Refers to the zero-point of the Hill-Van Vleck expression in the upper state. Dunn, Hanson, et al., 1970 give 16197.52, in poor agreement with our recalculated value 16197.21. We assume that the former is intended to be 16197.25.
