FIG. 1.

1 UV ionization spectrum and line assignments for the band of . The diamond-shaped symbols act as a guide to indicate the perturbed intensity pattern in the branch, where the 3:1 ratio between odd- and even- transition lines, arising from nuclear-spin statistics, has been taken into account.

Rotational term values for , , , and , for the three isotopomers of . For clarity, only the -parity levels are displayed. The symbols in gray represent data from the Harvard-Smithsonian molecular database (Ref. 34). Indicative energy levels (lines) were obtained using the CSE model. The missing rotational levels for were difficult to determine due to excessive predissociation and additional perturbation by the level.
