Infrared spectra and band strengths of the fundamental and first overtone of HCl and DCl in liquid xenon solutions

The band strengths of the fundamental and first overtone of HCl and DCl have been measured in liquid xenon solution. The fundamental increases in intensity while the overtone decreases in intensity relative to the respective gas phase values. A variety of simple models are applied to the system in an effort to explain the observed effects. The possible effect of HCl–Xe complexes on the spectra is considered.
