Photochemistry II: Electron Transfer Kinetics

This lecture delves into the dynamics of electron transfer reactions in photochemistry, focusing on the nuclear reorganization-controlled kinetics. It covers the Marcus-Levich theory, the formation of precursor complexes, and the geometrical derivation of the Marcus equation. The discussion extends to Marcus-Hush theory, the avoided crossing of potential energy surfaces, and the Marcus vs. Tafel equation. Additionally, it explores adiabatic vs. diabatic electron transfer processes, the nuclear reorganization energy, and Fermi's golden rule for diabatic electron transfer. Practical applications and theoretical implications are thoroughly examined.
