The DNA cleavage via superoxide anion, formed in photoinduced electron transfer from NADH to γ-cyclodextrin-bicapped C₆₀ in a oxygen-saturated aqueous solution, was discussed. The reorganization energy for the reduction of O₂ to O₂^.- was found to be 43.4 Kcal mol^-1. The analysis suggested that the electron transfer from C₆₀^.-/γ-CyD to O₂ proceeded via an outer sphere pathway.
