Center for the Study of Fast Transient Processes Annual Report October 1987 - December 1988
Abstract
This work is devoted to the study of high-energy collisions between polyatomic molecules and surfaces. Collision-induced chemical reactions are studied at several eV (usually < 10) incident kinetic energy. Under these conditions, the molecule surface interaction is impulsive (i.e. as near as can be determine, there is little or no sticking) and capable of distorting the molecule enough to induce unimolecular decomposition following collision with the surface. The first experiments on collision-induced-dissociation were with n-C3F7N0. The No fragment was detected state-selectively 2-photon 2-frequency laser ionization, and it proved possible to obtain high S/N with dissociation probabilities as low as 1%. A parallel set of photogragmentation studies with C3F6N0 was initiated and showed that many features of the surface-molecule. This suggest that the energized precursors are similar in the two experiments, and suggests further be the excited molecules may well dissociate via a unimolecular decomposition mechanism.
