โœฆ Synopsis

Energy transfer rate constants have been measured by the laser-induced fluorescence technique for the non-resonant vibrational deactivation of N, (u= I ) and '3C'60 (v-I ) by CH4 and O2 both in liquid N2 and in liquid Ar solution at 85 K. CO( v= 1) and Ns(n= I ) behave similarly in liquid Ar solution, but in liquid N, solution, large differences are found. These results show that in liquid Ar the vibrational excitation of a N2( v= I ) molecule is localised, whereas in liquid Ns solution the excitation is to some extent delocalised on to the surrounding N2 molecules. These solvent interactions with the vibrationally excited molecules render the isolated binary collision hypothesis inadequate for describing the molecular dynamics.

Rate constants for vibrational energy transfer have been measured in the system N2( v= 1) +CO( u= 0) as a function of energy mismatch by using isotopic derivatives of N2 and of CO. These rate constants have been determined both in the gas phase and in liquid argon solution at 8 5 K. For non-resonant
