Abstract: A new approach to the study of excited state radiation-less processes of large molecules in the vapor phase is proposed. The basis of the approach is the opto-acoustic effect, the generation of temperature and pressure fluctuations in a sample upon absorption of optical energy. The set of heat flow equations governing this effect are constructed and solved, under certain restrictions, for a sample in an isothermal cylindrical cell acted on by a short pulse of light. Computer simulations of the expected pressure signals are presented, and it is shown how molecular parameters can be extracted from experimental measurements. Limitations on experimental design imposed by theoretical assumptions are discussed and applied to the construction of an experimental system for performing time-resolved opto-acoustic spectroscopy. The properties of oxalyl chloride are examined, and it is chosen as the object of experimental study. An attempt to verify the theorecically .My predicted opto-acoustic signals using oxalyl chloride is made but is unsuccessful due to insufficient pulse energy from the excitation source employed. Improvements of the experimental system are suggested, and areas for future work are designated.
