摘要：

Low-lying electronically excited states of C60 and C70 were identified in picosecond transient absorption measurements extending in wavelength down to 1000 nm. Spectral features in the near-infrared region were found to be significantly different from the results of previous studies. The lifetimes for S1 states of C60 and C70 Were determined to be 1.3+/-0.2 ns and 0.7+/-0.05 ns, respectively. A simple energy diagram for electronic states of C60 and C70 is presented.
