Vibrational relaxation of HCI( v= 1) has been studied in mixtures with Kr and Xe at room temperature with the help of laserinduced fluorescence. Relaxation rate constants of k,,( Kr) =0.3 + 0.2 and k,,( Xe) = I. I f 0.3 Torr-' s-' have been found. The increase in the relaxation efftciency of xenon c

โฆ Synopsis
The vibrational relaxation of HCI in liquid xenon at -68ยฐC has been studied. Vibrationally excited HCI is created following UV photolysis of HCI. The rate of relaxation of HCl as a function of HCl mole fraction in liquid xenon is the same as the correspondingrate forgas phaseHCIat -68ยฐC. Similarly therate of relaxation of HCl in HCl-Xe 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.
