Two distinct Raman spectra have been reported for solid C-60 They differ in the exact position and relative intensities of the spectral lines. Specifically, the frequency of the pentagonal pinch mode occurs at 1469 and 1459 cm(-1) in the two spectra. Several explanations have been offered for the existence of a second spectrum, including the influence of interstitial oxygen, a change in phase, the coexistence of singlet C-60 with laser-pumped triplet C-60, and photopolymerization. We show that there are two Raman spectra for solid films of C-60 with varying relative intensities according to the sample temperature even in the absence of oxygen. The reversibility of the two forms of C-60 With temperature argues against photopolymerization. Finally pump-probe experiments designed to detect either triplet absorption or singlet depletion indicate that neither of the two Raman spectra are due to triplet C-60. We conclude that our previous explanation of C-60 is still the most consistent with the observations.
