Vibrational Deactivation of HF(v = 1) and DF(v = 1) by H and D Atoms

Abstract

The deactivation of HF(v = 1) and DF(v = 1) by H and D atoms was studied at 295 K by means of the techniques of laser-induced infrared fluoresence and isothermal calorimetry. The upper limits for the deduced rate coefficients are well-defined, but the lower limits are imprecise. The results of this study are compared with other experimental data and with trajectory calculations. Qualitative data are presented regarding the role of reactive, i. e., F-atom exchange, versus nonreactive collisions in the removal of the v = 1 level. A verification of the method was made by determining a rate coefficient for H + HCl(v = 1) that is in good agreement with a recent study.
