文摘

Inelastic neutron scattering spectra were measured at 85 K for a hydrofullerite quenched to this temperature after a synthesis at 620 K under a hydrogen pressure of 0.6 GPa, and for the same sample annealed at 300 K. The quenched sample consisted of C₆₀H₂₄ molecules and of interstitial molecular hydrogen (1.4 H₂ molecules per unit C₆₀). The interstitial H₂ left the sample during the anneling at 300 K. The intramolecular and intermolecular C₆₀H₂₄ vibrations and H₂ rotations are discussed based on the measured spectra.
