Competing Dissociation Channels in the Infrared Multiphoton Decomposition of Ethyl Vinyl Ether.
Abstract
Infrared multiphoton decomposition of ethyl vinyl ether (EVE) has been investigated by the crossed laser-molecular beam technique. Competition is observed between the two lowest-energy dissociation channels: (1) EVE yield CH3CHO + C2H4, and (2) EVE yield CH2CHO + C2H5. Center-of-mass product translational energy distributions were obtained for both dissociation channels. The products of reactions (1) and (2) are formed with mean translational energies of 31 kcal/mole and 5 kcal/mole, respectively. The branching ratio shifts dramatically in favor of the higher energy radical producing channel as the laser intensity and energy fluence are increased, in agreement with the qualitative predictions of statistical unimolecular rate theory.
