    • Single electron transfers may be categorized as outersphere and innersphere processes according to whether they are not or whether they are accompanied in a concerted manner with breaking or formation of bonds. The classification originates from the electron transfer chemistry of metallic complexes, 3b making a distinction between the reactions where one electron but no ligand is transferred and those where a ligand is transferred concertedly with one electron, which amounts for the transfer of an atom (or of a group of atoms). The notion was extended afterwards 3c according to the definition above so as to include all kinds of molecules, including organic molecules

    • Another approach deals with reactants anchored to the electrode surface. This strategy was applied to the reduction of ferrocene attached to the electrode surface by a long chain. 11b The pre-exponential factor is then much smaller than in the preceding cases, because of electron tunneling over a large distance. The small value of Z thus allows its determination together with its organization energy at a given temperature. The validity of the Hush-Marcus kinetic law could then be tested after introduction of the contribution of all electronic states of electrons in the electrode, which wipes out the inverted region predicted by eqn (1) 11c
