The equation posited by this theory sets a certain quantity equal to the intrinsic barrier multiplied by the quantity one plus standard free energy, corrected for electrostatic work, all divided by the reorganization energy.
In 1977, John Albery and Maurice Kreevoy extended this theory to methyl reactions by examining patterns of reactivity in SN2 reactions. The equation posited by this theory sets a certain quantity equal to the intrinsic barrier multiplied by the quantity one plus standard free energy, corrected for electrostatic work, all divided by the reorganization energy. An empirical equation known as Dutton's Ruler is the result of a namesake inversion region posited by this theory, a region where the reaction rate begins to drop off with increased driving rate. This theory was modified by Noel Hush to account for inner-sphere reactions where the relevant species are attached by chemical bridge. FTP, name this eponymous theory of electron transfer in physical chemistry.
