REDUCTION PATHWAYS OF INDIUM IONS - MULTISTEP DISCHARGE OR DISPROPORTIONATION

Alternative mechanisms for the discharge of indium(III) aquo complexes were discussed on the basis of charge-transfer theory in polar solven ts and of the methods of quantum chemistry. The components of solvent reorganization energy, the electrostatic parts of the energy of reacta nt and product approach, and the activation energies were estimated fo r consecutive multistep electron transfer and for bimolecular dispropo rtionation reactions. The importance of the preexponential factors was discussed It was shown that consecutive discharge is more likely.
