Infrared multiphoton dissociation of vinyltrifluorosilane

Infrared multiphoton absorption and dissociation of vinyltrifluorosilane molecules under the action of pulsed TEA CO2-laser were experimentally studied. The composition of the end dissociation products has been analyzed. Using quantum chemical calculations, we have identified the dissociation pathways that lead to the observed end products. Transition state geometries, enthalpies and activation energies for the dissociation pathways have been calculated. The dissociation channel ratio was determined under used experimental conditions. The silicon isotope selective infrared multiphoton dissociation has been performed at different wavelengths of the CO2-laser radiation.
