An outer-sphere ) electronic interaction between the reactants in the
electron transfer
is a reaction in which the electron transfer
takes place with no or very weak (transition state
. If instead the donor and the acceptor exhibit a strong electronic coupling
, the reaction is described as inner-sphere electron transfer
. The two terms derive from studies concerning metal complexes and it has been suggested that for organic reactions the terms 'nonbonded' and 'bonded' electron transfer
should be used.See also:
