It is the purpose of this paper to develop unified mathematical models for electron transfer reactions in condensed media. Using these models we will discuss the main qualitative features of these processes. Electron transfer reactions in the gas phase are reasonably well understood. In some cases the reaction is direct; in others it involves the formation of an unstable quasimolecule (of lifetime 10−13sec) posessing a full set of quantum numbers.1) 2) 3) 4) Using standard “adiabatic techniques” the processes can be described theoretically.5)6) In condensed media the situation is complicated by various factors such as:
  1. (1)

    Electrostatic interactions with the solvent that modify the energy levels and wave functions of the reactants.

  2. (2)

    Polarization changes in the solvent.

  3. (3)

    Bridge formation by solvent molecules.

  4. (4)

    Relaxation processes which do not occur in the gas phase.

  5. (5)

    The symmetry of interacting orbitals.
