Abstract
In this review branching between various exit channels of a chemical reaction is considered. Exit channels are here defined by chemical species, electronic state and charge state, while the finer branching between “internal” states is generally excluded. Classic as well as recent examples are discussed, drawn from many different areas: Neutral and ionic bimolecular reactions, chemiluminescence, chemiionization, charge transfer, Penning and associative ionization, excimer formation, electronic energy transfer, photodissociation. Only those examples have been included for which an explanation, however tentative, has been offered in the literature, and this theoretical background is sketched briefly in each case. The determining factors considered by various authors include effects of mass, orientation, geometry of the heavy particles; electronic symmetries, Woodward-Hoffmann rules, alignment, non-adiabatic transition requirements; energetics; time scales; shapes of potential curves or surfaces; statistics.
