Method to measure the relaxation rates of molecular levels
Abstract
The influence of buffer gases (He and SF6) on vibrational and relaxational rates has been studied. The line shapes (width and amplitude) of the small signal gain of the 119-micron methanol laser line are measured at different methanol vapor and buffer gas pressures using an infrared far-infrared double resonance method. The relaxation rates are calculated using the modified rate equations of the Henningsen-Jensen model.
