Abstract
One-photon laser excitation and subsequent bulk collisional relaxation of target molecu-les highly dispersed in a heat bath yields information about energy transfer in the bulk system Ca macroscopic time-dependent property], provided the internal energy of the target molecules is monitored as a function of time. If the relaxation of internal energy is ap-proximately exponential, it is possible to obtain the average energy transferred per collision Ca microscopic time-independent property] without knowledge of the collisional transition probability. The implication of exponential relaxation is that the first moment of the collisional transition probability is approximately a linear function of internal energy. These conclusions are illustrated using available laser relaxation data on azulene, benzene and hexafluorobenzene, and are compared with similar data on toluene and two cycloheptatrienes. Some inconsistencies are noted, the probable origin of which is discussed.
