Near IR TDLS study of the HF first overtone line shape. II. Theoretical analysis

Abstract

Results of a theoretical study of the HF first overtone rovibrational absorption spectral line profile (the transition 0-2 R(0)), broadened by Ar (mixture HF : Ar = 1 : 150, T = 295 K, P = 10-300 mm Hg) are presented. The generalized Ciurylo-Pine-Szudy line shape model was selected for the analysis of different factors influencing the spectral line shape. The shortcomings of this model are revealed via validation of its basic assumptions, using the classical trajectory method. Special consideration is given to the elucidation of the nature of the anomalous asymmetry of the HF spectral line shape.
