IR–IR double-resonance studies of vibrational relaxation of CD3F in solid and liquid Xe, Kr, Ar solutions near the melting point Original Research Article

Vibrational energy relaxation has been studied for CD3F diluted in liquid and solid Xe, Kr, Ar near the melting points. On solidification of the Xe and Kr, a hopping increase of the relaxation time is revealed, whereas the liquid to solid-state transition in Ar solution is accompanied by a small decrease in time. The temperature dependence of the vibrational relaxation rate, obtained on the basis of low-density gas-phase, liquid, solid and low-temperature matrix measurements, is discussed in terms of simple binary and collective approaches.
