Abstract
Pressure-broadening parameters of 25 lines belonging to the ν band of OCS in collision with O have been measured with a tunable diode-laser spectrometer. From these coefficients and previously measured N-broadening coefficients, smoothed values of air-broadening parameters of OCS have been derived. The experimental results for O broadening are compared with values calculated on the basis of the Anderson-Tsao-Curnutte theory and an improved semiclassical impact theory in which we used a simple formalism for the nonelectrostatic anisotropic potential. The latter theory, which has also been applied by considering an atom-atom interaction model, yields results in overall agreement with experimental data.
