Flow Tube Studies of the Deactivation of HF(V) by Selected Polyatomic Molecules.
Abstract
A large-diameter, medium-pressure flow tube has been used to study deactivation processes by selected polyatomic molecules that are potentially relevant in chemical laser systems. Effective vibrational deactivation rate constants for HF(v = 1,2,3) relaxed by H2S, CO2, N2O, CH4, CF4, and SF6 have been determined. The rates for a given chaperone increase with increasing v. The agreement with results for HF(1) + M reported from laser-induced fluorescence experiments is generally very good. The role of HF rotational energy in absorbing a vibrational energy defect is examined. An empirical correlation with adjusted vibrational energy defect is suggested.
