title: N(2) Broadening of Carbon Disulfide (12)C(32)S(2) in the nu(3) and nu(3)-nu(1) Bands.
abstract: N(2) broadening coefficients have been measured for 33 lines in the nu(3) fundamental band and 21 lines in the nu(3)-nu(1) band of C(32)S(2), using a tunable diode-laser spectrometer. These lines with J values ranging from 0 to 78 in the nu(3) band and from 4 to 70 in the nu(3)-nu(1) band are located in the spectral ranges 1514-1548 and 853-887 cm(-1), respectively. The collisional widths are obtained by fitting the spectral lines with a Voigt and a Rautian profile. Semiclassical calculations of these broadening coefficients have been performed by considering, 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.
