Ar- and air-broadening coefficients in the ν3 band of CS2 at room and low temperatures

摘要: Abstract Using a diode-laser spectrometer, Ar-broadening coefficients for 16 spectral lines in the fundamental ν 3 band of CS 2 have been measured at five temperatures: 298.0, 273.2, 248.2, 223.2 and 198.2 K. These with J values ranging from to 64 are located range 1519–1547 cm −1 . The broadening also calculated semiclassical impact model performed by using simple empirical intermolecular potential. From theoretical experimental results obtained different temperatures, we determined n exponent governing temperature dependence coefficients. air-broadening four experimentally same temperatures. They compared derived those previously perturbers N , O Ar.
