Low-N lines of the A(6)Sigma(+)-X-6 Sigma(+) (1,0) band of CrH

{The (1,0) band of the A(6)Sigma(+) - X-6 Sigma(+) 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 a(4)Sigma(+)
