VERTICAL IONIZATION ENERGIES AND ELECTRON-AFFINITIES OF IONS IN SOLUTION FROM OUTER-SPHERE CHARGE-TRANSFER TRANSITION ENERGIES

Outer-sphere charge transfer (OSCT) transitions are shown to correlate with previously published photoelectron emission threshold energies. From these data it is possible to generate a set of parameters, I-D an d I-A, which define these OSCT energies, where I-D is identified as th e solution phase vertical ionization potential, and I-A is the solutio n phase vertical electron affinity. An easy procedure for deriving the se data for a wide variety of cations and anions is presented. The app lication of these data leads to a powerful procedure for extracting re organization and solvation energies of value in a variety of applicati ons.
