Bulk C60 has been treated at 1.1 GPa and 550-585 K, producing a dense insoluble material which on heating to above 600 K reverts to normal C6o. Raman and IR studies on modified material show a large number of new lines, and the Raman pentagon pinch mode shifts from 1469 to 1458 cm-1 as on photopolym

We have used an approximate first-principles method together with a bond-polarizability model to calculate theoretical Raman spectra for the orthorhombic (O), tetragonal (T), and rhombohedral (R) phases of pressure-polymerized C 60 solid. We have also calculated Raman spectra for a sequence of C 60
## Abstract Highβpressure Raman spectra of fullerite, a solid form of C~60~, were measured at pressures up to 4 GPa and room temperature. A change of slope (d__v__/d__P__) of the frequencyβpressure plots for the __A__~g~ pentagonal pinch mode and the __A__~g~ breathing mode was observed at 1.3 GPa,
