Abstract

Abstract: The gas-phase photodissociation of an unsymmetrical azoalkane, 3-(methylazo)-3- methyl-l-butene, was studied with time-resolved coherent anti-Stokes Raman spectroscopy (CARS) to probe for product formation. Appearance kinetics were measured for all three primary photoproducts. The results indicate a two-step dissociation mechanism in which the 1, l-dimethylallyl fragment is formed within 2 ns of excitation, whereas the methyl radical ...
