Marcus Theory Calculator
Calculate electron transfer rates and activation barriers using Marcus theory
About Marcus Theory
Marcus theory describes electron transfer reactions and predicts the famous "inverted region" where reactions become slower as the driving force increases beyond the reorganization energy.
- Normal region: |dG°| < Lambda - rate increases with driving force
- Optimal: |dG°| = Lambda - barrierless, maximum rate
- Inverted region: |dG°| > Lambda - rate decreases with driving force
