摘要：

We report Raman measurements on the photoinduced disassociation via a metastable excited state intermediate of the photoproduct formed from the photochemical degradation of C-60. At low intensities, the intrinsic 1468cm(-1) C-60 mode softens to 1459cm(-1), which is stable below an apparent threshold intensity above which it shifts abruptly to 1463cm(-1) This mode is stable with increasing intensities. Upon a return to low intensities, the 1468cm(-1) intrinsic C-60 line reappears. The positioning of the Raman line at 1463cm(-1) is associated with an excited state intermediate, observable only at high excitation densities.
