Abstract

Intermolecular vibrations in a variety of fullerene systems are reported that provide information on C60-C60 and alkali-metal - C60 interactions and disorder effects. Low frequency Raman scattering in laser polymerized C60 films are shown to exhibit additional modes not reported for bulk materials. This result is consistent with recent dimer calculations. Raman scattering and HREELS measurements are shown to provide complementary information on alkali-metal motions in K3C60. In FCC Na6C60 both octahedral site disorder effects and reduced Na-C bond lengths account for changes in the Raman spectrum relative to Na3C60.
