摘要：

The photoexcited triplet of C70, in toluene, was investigated by time-resolved EPR spectroscopy. Over the entire range of temperatures (8-213 K) the resulting early-time signal is attributed to the polarized EPR triplet spectrum, which evolves in time into a thermalized spectrum. Similar to the case of C-3(60), the narrow liquid-phase spectrum is due to rotational narrowing of the thermal triplet. At both low and high temperatures the results indicate the coexistence of two triplets, differing greatly in their relaxation rates.
