PROTON-TRANSFER REACTION DYNAMICS

In this article we discuss the progress made in understanding intramol ecular and intermolecular reactions of proton (or hydrogen-atom) trans fer. Femtosecond real-time probing, together with spectroscopic studie s, in molecular beams are presented with selected examples of reaction s. Reaction rates, tunneling dynamics and the nature of the reaction c oordinate are examined and related to two-state multidimensional poten tial energy surfaces.
