Rotational Relaxation Studies of HF Using Double I.R. Resonance.
Abstract
Rotational relaxation effects in HF were observed with double resonance IR experiments that employed two single wavelength lasers. A pulsed laser is used to pump the population to a particular V,J level, and the absorption of stable cw laser radiation is used as a probe to determine the loss or arrival of population in specific J levels. Results are described for both the rotational transfer rates and the temporal behavior of the population distribution over rotational levels after the population was placed in a single level. Rotational transfer rates were found to be three orders of magnitude faster than V-T relaxation and to depend on Delta J. (Also the effects of foreign gases were investigated.)
