Preferred Label : outer-sphere electron transfer;
IUPAC definition : An outer-sphere electron transfer is a reaction in which the electron transfer takes
place with no or very weak (4-16 kJ mol-1) electronic interaction between the reactants
in the 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.;
