Marcus theory

Marcus theory, named after chemist Rudolph A. Marcus, is a theoretical framework used to describe electron transfer reactions in chemistry. Specifically, it provides insights into the rate of electron transfer processes, which are fundamental to many chemical reactions, including those in electrochemistry, biological systems, and materials science. The key aspects of Marcus theory include: 1. **Potential Energy Surface**: The theory describes the energy changes associated with the electron transfer reaction using a potential energy surface.
