Abstract
The study of molecular beam scattering from solid surfaces /1/ combined with state-selective laser techniques for the diagnostics of the scattered molecules allows us to address some fundamental problems concerning the dynamics of the molecule-surface interaction. This problem is particularly intriguing compared to the one occurring in molecule-molecule collisions since the degrees of freedom of the two interacting partners are of fundamentally different character, individual and collective/ respectively. The way the different degrees of freedom adapt to each other during the scattering process, how they exchange energy or how they equilibrate is of paramount fundamental and technological interest. Accordingly/ in order to extract the relevant information from these investigations it is essential to maintain the specificity of each part, of the molecule as well as of the surface, in the description of the interaction and in the interpretation of the results.
