Low-N lines of the A6Σ+–X6Σ+ (1,0) band of CrH

Author affiliations

Abstract

The (1,0) band of the A6Σ+–X6Σ+ electronic transition of CrH has been observed by laser-induced fluorescence following the reaction of laser-ablated Cr atoms with methanol under supersonic free-jet cooled conditions. Rotational assignments of the levels with N ≤ 3 have been made by combination differences and dispersed fluorescence experiments on selected lines. These assignments complement those made from previously-recorded Fourier transform emission spectra, in which higher-N lines were assigned. The low-N rotational levels are extensively perturbed, presumably by levels of the a4Σ+, υ = 1 and B6Π, υ = 0 states.
