The Raman A(g)(2) mode of C-60 fullerene has been used as a probe. The spectra were measured using seven different laser excitation energies. For cathodic charging we observed bleaching of the A(g)(2) mode independent of laser excitation energy. Oil the other hand for anodic charging the behavior of the A(g)(2) mode was dependent on laser excitation energy. The intensity of the A(g)(2) mode decreased only for the 1.16 eV laser excitation energy. In the case of other laser excitation energies (2.70, 2.60, 2.54, 2.41, 2.33, 2.18 eV) an increase of intensity has been observed. The dependence of the slope of the intensity on the electrode potential has been found to be a function of laser excitation energy.
