We report the first low temperature measurements on the collisional relaxation of toluene molecules initially containing high amounts of internal excitation. These highly excited toluene molecules are generated by photoisomerization of cycloheptatriene molecules that are excited by irradiation with the output of an excimer laser operating at 248 nm. These measurements have been performed on very dilute mixtures of cycloheptatriene in He, Ar, or NZ carrier gas in a CRESU (Cinetique de Reaction en Ecoulement Supersonique Uniforme) apparatus. Collisional relaxation of the excited toluene molecules is followed by observing their time-resolved infrared fluorescence. Analysis of the results allows us to infer how the average energy removed per collision, [[DeltaE]], varies with the average energy contained in the toluene molecule, [[E]], for toluene-He collisions down to 38 K, for toluene-Ar collisions down to 112 K, and for toluene-N-2 collisions down to 74 K. In no case is the variation of [[DeltaE]] with temperature strong. However, in the case of toluene-He, the trend is for [[DeltaE]] to decline with temperature, whereas for toluene-Ar and toluene-N-2 [[DeltaE]] is essentially independent of temperature. It is suggested that these results may reflect the relative influence of the van der Waals forces in inducing energy transfer.
