✦ Synopsis
Infrared fluorescence and double infrared resonance have been used to measure the V-T relaxation of CD3F and CD 4 in mixtures with He, He, At, Kr, Xe and HCI in the gas phase and in the liquid Ar, Kr, Xe. It is shown that the temperature dependence of V-T probabilities in the interval 350-150°K can be attributed to an increasing influence of long range forces. In the mixture CD3F + HCI, where Hbonded complexes CD3F...HCl have been formed, the vibrational relaxation rate considerably increases with decreasing temperature. It is found that the probabilities of V-T energy transfer in cryogenic solutions are lower than those measured in the gas phae.
