چکیده انگلیسی
Using a diode-laser spectrometer, Ar-broadening coefficients for 16 spectral lines in the fundamental ν3 band of CS2 have been measured at five temperatures: 298.0, 273.2, 248.2, 223.2 and 198.2 K. These lines with J values ranging from 2 to 64 are located in the spectral range 1519-1547 cmâ1. The broadening coefficients are also calculated from a semiclassical impact model performed by using a simple empirical intermolecular potential. From the theoretical and experimental results obtained at the different temperatures, we have determined the n exponent values governing the temperature dependence of the broadening coefficients. The air-broadening coefficients for four spectral lines in the ν3 band of CS2 have also been measured experimentally at the same temperatures. They are compared to the values derived from those obtained previously for the perturbers N2, O2 and also Ar.
