Notes

1It is possible that more than one transition is involved.
2Very diffuse bands. 1
3Doublet separation ~20 cm-1.
4Only v'=2 progression observed.
5Predissociation begins between v'=1 and 2.
6Bands in the region 17000 - 23000 cm-1. Different vibrational analyses, omegae' ~ 190 cm-1.
7Extrapolation of vibrational levels in A': atomic products at the limit uncertain.
