Abstract
High-pressure phases of C60 fullerene similar to those reported by Iwasa et al. were obtained at a non-hydrostatic pressure of 3 GPa and different temperatures in the 100-500 degrees C range. The substances were investigated by means of infrared, optical and micro-Raman spectroscopies. Compared with pristine C60, the spectra of the transformed material reveal multiple changes which depend systematically on treatment conditions. They evidence a substantial modification of selection rules for allowed optical transitions apparently due to formation of C60 molecules with deformed and/or partially destroyed cages.Keywords
