Diffusion Mechanisms of Flexible Molecules on Metallic Surfaces
The dynamics of flexible molecules in condensed phases is a subject of intense investigation for a variety of systems. Particularly relevant to heterogeneous chemical catalysis is the behavior of large flexible molecules adsorbed to metallic surfaces. Transition metals serve as catalysts for a variety of organic reactions and so the diffusion dynamics of organic molecules on such surfaces are especially important. In addition, the inter-relationship among internal degrees of freedom and cohesive motion of the molecules constitutes a complex subject rich in intriguing phenomena. The purpose of the present paper is to delineate some of these relationships for systems of relevance to heterogeneous chemical catalysis.
