摘要：

The extinction coefficients of the triplet state of C60 are obtained by energy-transfer techniques in flash photolysis studies. The values permit actinometric measurement of the triplet quantum yield (phi(R)=0.93+/-0.07) and give rates of T-T annihilation close to diffusion-controlled. Rates and radical quantum yields in reversible one-electron reduction of C-3(60) by tri-p-tolylamine, TTA, and hydroquinone are determined as well as extinction coefficients in the visible of the C60- anion radical. Back electron transfer from C60- to TTA+ occurs at a distance markedly greater than van der Waals contact.
