Abstract
The CN(B2SIGMA+) radical was produced in a jet using an electric dc di scharge of the precursor CH3CN with inert carrier gases. The rotationa lly resolved Fourier transform emission spectra of the 0-0 band of the B2SIGMA+-->X2SIGMA+ transition of CN have exhibited different distrib ution of the intensity for the carrier gases He and Ar, respectively. From the analysis of intensity distribution in the spectra, the mechan ism for rotational cooling process of CN radical in a supersonic expan sion has been suggested.
