Low-N lines of the A6sigma+-X6sigma+ (1,0) band of CrH.
The (1,0) band of the A6sigma+-X6sigma+ 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 < or = 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 a4sigma+, upsilon = 1 and B6pi, upsilon = 0 states.
