Gibbs energy dissipated when a system that has undergone 'vertical
' electron transfer
(i.e., electron transfer
obeying the Franck–Condon principle
) relaxes to the
equilibrium state for its new charge distribution. Commonly the total reorganization
is written as the sum of an inner contribution
and an outer contribution
attributed to nuclear reorganizations
of the redox partners and their environment (solvent), respectively.
Approximations have been proposed to calculate the value of
taking into account the 'relative permittivity
' of the solvent.
