✦ Synopsis

The self-broadening coefficients and the intensities of 29 lines in the ν 1 band of cyanogen chloride ( 35 Cl 12 C 14 N) have been measured at high resolution in the range 699-736 cm -1 , using a tunable diode-laser spectrometer. The collisional widths and most of the intensities are obtained by fitting Voigt and Rautian profiles to the measured shapes of the lines. From the analysis of the line intensities we determine the absolute strength as well as the Herman-Wallis factors for the ν 1 band. A semiclassical calculation of the self-broadening coefficients, performed by considering the main electrostatic interactions only, has provided larger results than the experimental data.
