Extended analysis of the B2Σ+–X2Σ+ and A2Π–X2Σ+ systems of ZrN

Abstract

Rotationally resolved spectra of (1,0), (1,1), (2,0), (2,1) and (2,3) bands of B2Σ+–X2Σ+ and (3,3) band of A2Π–X2Σ+ systems have been measured in a laser-induced fluorescence spectra of jet cooled ZrN molecule. Rotational analysis have been extended to include the levels ν=3 of X2Σ+, ν=1,2 of B2Σ+ and ν=3 of A2Π states. The vibrational constants of the X2Σ+ state have been determined. Perturbations were observed in all the rotational branches of the B–X system and A2Π1/2f–X2Σ+ subband.
