Preferred Label : inverted region (for electron transfer);
IUPAC definition : In plots relating rate constants to charges in standard Gibbs energy (ΔG ) for electron
transfer a region may occur in which the rate constants decrease as the exergonicity
of the reaction increases. This region is often referred to as the inverted region
and its presence is predicted by the theory developed for outer sphere electron transfer
for the case -ΔG λ in the Marcus equation, λ being the reorganization energy. Note
the similarity to the energy gap law for radiationless conversion of an excited state.;
