Abstract
The electron transfer process between Ru(NH3)(5)pz(2+) and S2O82- has been studied in different water-cosolvent mixtures. The results are explained as suming an additional component of the reorganization free energy of the sol vent in the mixtures. This new component is caused by a translation of the solvent molecules and it is a consequence of the changes in the composition of the (at least) innermost solvation shell of the reactants produced by t he electron transfer. An attempt to quantify this additional reorganization energy is made. (C) 1999 Elsevier Science B.V. All rights reserved.
