✦ Synopsis

Thin Cu-C 60 films were prepared by vacuum co-deposition and investigated by Raman spectroscopy. Evidence was found for alteration of the intramolecular vibrational modes of C 60 due to the presence of Cu and also for activation of silent modes. The effects were attributed to the interaction at the interface between the metal and fullerene and to the related formation of interstitial metallic ions. This hypothesis is supported by structural evidence derived from x-ray diffraction and EXAFS.

Low-frequency vibrational features are observed m the enhanced Raman spectra from an electrochemically roughened Ag electrode. Evidence is found that these features are related to resonant Raman scattermg from the internal vibrations of small Ag clusters stabilized on the surface. Comparison of the
