Kr-broadened halfwidths of twenty-eight lines in the ν1 band of OC32S have been measured from absorption spectra recorded at room temperature with a tunable diode laser spectrometer. The results are compared to values calculated on the basis of the Anderson-Tsao-Curnutte theory and an improved semiclassical impact model developed by Robert and Bonamy. Both theories have been applied from a Smith-Giraud-Cooper intermolecular potential by considering the potential coefficients as adjustable parameters. Moreover, an atom–atom interaction model was used in the latter theory.
