Temperature and Polarizability Effects on Electron Transfer in Biology and Artificial Photosynthesis


Abstract This study aims to address the deficiencies of the Marcus model of electron transfer

(ET) and then provide modifications to the model. A confirmation of the inverted energy

gap law, which is the cleanest verification so far, is presented for donor-acceptor complexes.

In addition to the macroscopic properties of the solvent, the physical properties of the solvent

are incorporated in the model via the microscopic solvation model. For the molecules

studied in this dissertation, the rate constant first increases with cooling, in contrast to the

prediction of the Arrhenius law, and then decreases at lower temperatures. Additionally,

the polarizability of solute, which was not considered in the original Marcus theory, is included

by the Q... (more)
