摘要：

High-pressure Raman spectra of fullerite, a solid form of C60, were measured at pressures up to 4 GPa and room temperature. A change of slope (dv/dP) of the frequency-pressure plots for the A(g) pentagonal pinch mode and the A(g) breathing mode was observed at 1.3 GPa, where a solid-solid phase transition might occur. The phase transition was observed to be irreversible. The pressure dependence of the Raman mode frequency and the phase transition are discussed in terms of an orientational ordering transition in fullerite.
