Abstract

The symmetry lowering by the crystal field in solid C60 leads to Davydov splittings and activation of molecular modes, as observed by Raman spectroscopy on single crystal C60- The influence of 514 nm irradiance on the Raman spectrum of C60 is discussed in terms of the long living excitonic triplet state of C60- At high irradiance the measured spectrum shows the vibrational properties of the excited state, rather than those of the ground state. The model used also explains the influence of the presence of oxygen on the Raman spectrum.
