Experimental studies of unimolecular reaction dynamics using direct excitation of overtone vibrations in combination with time-resolved spectroscopic product detection provide detailed data on unimolecular decomposition rates and energy disposal into the fragments of selectivity excited molecules. We have measured the reaction rate of tetramethyldioxetane at several energies using chemiluminescence detection and have constructed a pulsed molecular-beam apparatus for extending these measurements to cold molecules. We have also used laser-induced fluorescence detection to measure the unimolecular decay rate in selectivity excited t-butylhydrperoxide and to determine the product quantum states populated in the decompisition of hydrogen peroxide and its partially deuterated analogue. 3 figures.
