The Pressure Broadening of HDO by O2, N2,H2, and HE Between 100 K and 600 K

Abstract

Microwave transitions of HDO pressure-broadened by H2, O2, N2, and He were studied in the temperature region between 100K and 600K. Measurements below 250K were made in a collisionally cooled cell. Above this temperature a conventional equilibrium cell was used in the region where the HDO has non- negligible vapor pressure. Significant variations in both the pressure broadening parameter and its temperature dependence were observed among the studied transitions. Ordinarily, a power law is used to describe this temperature dependence. Deviations from this were observed below 150K.
