https://doi.org/10.1351/goldbook.C00999
A process in which, under the influence of a suitable @D01860@ (e.g. provided by @P04613@), electronic charge moves in a direction that increases the difference in local charges between donor and acceptor sites. @E02011@ between neutral species is one of the most important examples.
