Diode-Laser Measurements of Absolute Line Intensities in the ν1 Band of Cyanogen Chloride

With a tunable diode-laser spectrometer, absolute line intensity measurements have been made in the spectrum of cyanogen chloride in the vicinity of 710 cm−1. The intensity of the fundamental ν1 band has been found to be 6.088 cm−2 atm−1 for the 35ClCN isotopomer and 7.121 cm−2 atm−1 for the 37ClCN form. The influence of the Fermi resonance on the band intensity has been analyzed.
