Abstract
The ultraviolet bands ofA 1Π-X 1Σ+ system of As14N and its isotopic species As15N were excited in a quartz tube containing specpure nitrogen and traces of AsCl3 vapour, using a microwave discharge (2450 MHz). Bands of As15N were obtained using15N2 enriched to 95.5%. Rotational structure of several bands of As14N and As15N photographed under high dispersion (0.14 Å/mm) was reanalysed. Detailed studies of the observed perturbations in the levels ofν′ = 0 to 4 led to the identification of two3Σ− and aC 1Σ− states. Molecular parametersT e, ωe, ωexe, Beandα ewere determined for all the electronic states studied. Vibrational assignments of the perturbing levels were made using the isotope shift studies.
