The N2-, O2-, and air-broadened halfwidths and line mixing parameters of the N2O molecule and their temperature dependences
Broadening and line mixing parameters for N2-, O2-, and air-broadened N2O transitions in the ν1 band are investigated over temperatures ranging of 195 to 350 K, using the Refined Robert Bonamy formalism. The theoretically predicted halfwidths show very good agreement with experimental data from the literature, leading to a reliable prediction of the rotational dependence of the temperature exponent N. Since our model yields the full relaxation matrix W, it also enables calculation of Rozenkranz line mixing parameters. Based on the reasonable agreement with available data at room temperature, the temperature dependence of the Rozenkranz parameters has been analyzed, and its physical origin is briefly discussed.
