Rotational Relaxation Studies of Hydrogen Fluoride.
Abstract
Two double laser resonance experiments of collisional hole filling and vibration to rotation transfer have been used to determine rotational relaxation rates for hydrogen fluoride. The rates for rotational levels J2 through J14 range from 55,000,000/sec/torr to 2,000,000 sec/torr and these results are described by kinetic rate models. the rates increase with temperature by about 20 percent 300 K and 1000 K. The effect of several added gases on the rates has been measured. Vibration to rotation transfer proceeds by the accepted vibrational relaxation rate. A significant fraction of V=1 population is transferred with about 35 percent passing through the levels J10 - J14 of V=0. Originator-supplied keywords include: Relaxation rates, V-R transfer, Hydrogen fluoride, Rotational population transfer, and Chemical lasers.
