Résumé

Using a tunable diode laser spectrometer, we have measured O broadening coefficients of CS for 31 lines in the ν fundamental band near 6.5 μm and-12 lines in the ν - ν band near 11.4 μm. The collisional halfwidths are obtained by fitting the spectral lines with a Voigt and a Rautian profile. The broadening coefficients of CS-O are also calculated from semiclassical theory involving, in addition to electrostatic interactions, successively the atom-atom Lennard-Jones model and a simple formulation for the anisotropic dispersion forces, leading to more satisfactory results.
