Simplified models for the temperature dependence of linewidths at elevated temperatures and applications to CO broadened by Ar and N2.
Abstract
The broadening coefficients for i.r. lines of CO perturbed by Ar are calculated in the temperature range 300 - 3500K. The results are compared with high-resolution spectroscopic measurements of shock-heated CO-Ar gas mixtures. A simplified model is proposed to describe the temperature dependence of the linewidths. The resulting model is applied to CO broadened by N2 and the results are critically discussed.
