We report on the observation of two different triplet states in photoexcited C, fullerene molecules. The following fine structure parameters were determined from spectral fits to the triplet powder spectrum: IDI [=0.0117 cm-' (12.5 mT), lJ&l=O.O014 cm-' (1.5 mT) and / D2j ~0.0047 cm-' (5 mT), l&l =O

The triplet states of C6,, and C,,, (fullerenes) in solid phase at 3 and 77 K are detected by the time-resolved EPR technique. The observed time-resolved EPR spectra and the time profiles of the transient signals indicate that the geometries of Cw and CT0 are distorted from the soccerball geometry (
