| Abstract: | Using a tunable diode laser spectrometer, we have measured O2 broadening coefficients of 12C32S2 for 31 lines in the v 3 fundamental band near 6.5 μm and 12 lines in the v 3—v 1 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 12C32S2-O2 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. |
