Pressure-Broadening Effects In Mixtures Of Methyl Chloride And Non-Polar Gases At Microwave Frequencies

Abstract

Absorption measurements using 3 cm microwave resonant-cavity techniques have been performed on binary mixtures of methyl chloride and five non-polar gases (CO., Ar, N., He, H.l at pressures up to 4, atm. The results have been analysed in terms of the pressure-broadening theory of Van Vleck and Weisskopf, modified to include the effects of many-body collisions and a distribution of line widths.
