The pressure-broadening coefficients for a number of spectral lines ranging from|m| = 1to 58 in the v band of OCS, have been measured for collisions with Ar and CO with a tunable diode-laser spectrometer. The results are compared with values calculated on the basis of the Anderson-Tsao-Curnutte theory and an improved semi-classical impact theory. For OCS-Ar, we have used the Tipping-Herman intermolecular potential, as well as an atom-atom interaction model. For OCS-CO, we have considered, in addition to electrostatic interactions, successively a simple formalism for the anisotropic dispersion forces and the atom-atom interactions.
