โœฆ Synopsis

Molecular dynamics simulations of the dissociation of I, embedded in large Ar, (n = 319, 553) clusters, which impact at high velocities (u = 7-15 km s-l> on Pt surfaces, result in information on heterogeneous and homogeneous dissociation mechanisms. A broad distribution of dissociation lifetimes is exhibited, which can be attributed to prompt and retarded heterogeneous dissociation and to prompt, retarded and outbound homogeneous dissociation events. The propagation of a microshock wave within a large cluster can be interrogated by the homogeneous dissociation of a chemical probe, with the velocity of the propagation of the dissociation front being close to the cluster impact velocity.

The unimolecular decomposition of single ethylene ions in association with argon clusters containing more than 100 atoms has been observed. Fragmentation on these large clusters provides strong support for the proposal that a charge-transfer mechanism is responsible for exciting the molecular ions.
