Line frequency shift measurements by diode-laser spectroscopy for CH(3)D-Xe

Spectrochim Acta A Mol Biomol Spectrosc. 2004 Dec;60(14):3319-23. doi: 10.1016/j.saa.2003.12.054.

Abstract

The pressure-induced Xe shifting and broadening coefficients for five lines of 12CH(3)D in the nu(3) band near 7.5 microm have been measured using a tunable diode-laser spectrometer. The frequency shift was determined from the simultaneous record of the Xe-broadened line and the same line of pure CH(3)D at low pressure. Comparisons are made with the results of theoretical calculations based on a semiclassical model involving the atom-atom Lennard-Jones (LJ) potential.
