REORGANIZATION FREE-ENERGY FOR ELECTRON-TRANSFER REACTIONS AT LIQUID LIQUID INTERFACES/

Exact expressions for the reorganization free energy for an electron t ransfer reaction at the liquid/liquid interface are derived using elec trostatic continuum theory. All possible locations of the ions, includ ing the cases where one or both ions are located across the interface, are considered. The resulting calculations show that allowing for ion crossing at the interface has a marked effect on the reorganization f ree energy, and thus on the activation free energy, for electron trans fer.
