✦ Synopsis

The A 1 P -X 1 S / system of the PN molecule has been reexamined via high resolution conventional spectroscopy, at higher rotational J-values than those in previous studies. It is shown that perturbations occurring in the A 1 P (£ Å 0 to 3) levels give access to information concerning the (e 3 S 0 , a 3 S / , d 3 D, C 1 S 0 , D 1 D) valence states. Of particular interest are (1) the strong spin -orbit interaction between the e 3 S 0 and A 1 P (£ A Å 2) levels, yielding 17 rotational energy levels of the e 3 S 0 state, and (2) the triple crossing occurring between the A 1 P (£ A Å 3), d 3 D, and C 1 S 0 levels.

Polarization labelling spectroscopy of the B 1 ← X 1 + and C 1 + ← X 1 + band systems in KLi reveals strong mutual perturbation of the B and C states. We show that both excited states can be described in a model comprising numerical IPA potentials for the unperturbed states and only 3 parameters to

In the 13 CH / isotopic ion radical emission spectra of six bands of the A 1 P-X 1 S / system have been obtained using a Geissler-type discharge tube. The spectra have been photographed at high resolution and Th standard lines have been used as a calibration spectrum. The 1-1 band has been observed
