Vibrational Relaxation in Hydrogen-Carbon Monoxide and Deuterium-Carbon Monoxide Mixtures,Measured via Stimulated Raman-IR Fluorescence.

摘要

Rate constants for vibration-vibration and vibration-translation energy transfers were measured by exciting the hydrogenic spaces in a stimulated raman cavity and recording the subsequent rise and decay of IR fluorescence from the admixed CO at 4.7 micrometers. Under the justifiable assumption that the intraspecies redistribution of vibrational energy is very rapid, the time variation of fluorescence intensities and their dependence on the sample composition can be accounted for.
