The pressure behavior of the intramolecular phonon modes of the fullerene C84 and its structural stability have been studied for the first time by means of Raman spectroscopy and synchrotron X-ray diffraction at high pressure up to ∼10 GPa. The volume of the cubic unit cell has been measured as a function of pressure. The experimental data fitted by the Mumaghan equation-of-state (EOS) gave K0 = 19.5 ± 0.9 GPa and K′0 = 16.4 ± 0.6. The pressure coefficients and Grüneisen parameters of the intramolecular phonon modes of C84 have been determined and compared with those of other fullerenes. The data obtained do not show any phase transition and the pressure behavior of the material is entirely reversible in the pressure region investigated.
