Unimolecular dynamics of internal energy selected molecules
Abstract
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 were studied. The reaction rate of tetramethyldioxetane at several energies using chemiluminescence detection was measured and a pulsed molecular beam apparatus for extending these measurements to cold molecules was constructed. 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 decomposition of hydrogen peroxide and its partially deuterated analogue are used.
