The vibrational relaxation of HCl in liquid xenon at -68°C has been studied. Vibrationally excited HCl is created following UV photolysis of HCl. The rate of relaxation of HCl as a function of HCl mole fraction in liquid xenon is the same as the corresponding rate for gas phase HCl at -68°C. Similarly the rate of relaxation of HCl in HClXe collisions is in good agreement with the corresponding gas phase rate. These observations imply that the isolated binary collision model is valid for this system.
