HIGH-RESOLUTION STUDY OF V(3)+V(2) AND ASSOCIATED HOT BANDS OF CYANOGEN CHLORIDE

The nu(2) + nu(3) and associated hot bands of various isotopes of ClCN have been measured with a resolution of 0.0026 cm(-1) using a Fourier transform spectrometer. The wavenumbers of 4000 lines obtained from a bsorption spectra of three different isotopic species are measured wit h an accuracy better than 6 x 10(-4) cm(-1). Twelve bands of (ClCN)-Cl -35-C-12-N-14, six bands of (ClCN)-Cl-37-C-12-N-14, and one band of (C lCN)-Cl-35-C-13-N-14 were analyzed to obtain band origins, rotational constants, and l-doubling constants.
