Abstract
The ultraviolet band systemsA 1Π-X 1Σ+ of P14N and P15N were excited in an electrodeless tube containing traces of phosphorus specpure nitrogen and neon using a microwave discharge (2450 MHz). Bands of the isotopic species, P15N, were obtained using15N2 enriched to 95.5%. Rotational analyses of eleven bands of P14N and sixteen bands of P15N were carried out. Three perturbing statese 3Σ−,d 3Δ andb 3Π, arising from the lower valence configurations were identified from the observed perturbations in thev′=0–4 levels of theA 1Π state. Deperturbation studies led to the determination of molecular constants of the perturbing states. Vibrational assignments of the perturbing states were made from isotope shift studies.
