摘要：

The Raman spectra of various organometallic complexes of C60 have been obtained and compared to the Raman spectrum of unsubstituted C60. The reduction in symmetry of the molecular system is clearly demonstrated by the appearance of vibrational modes which were symmetry forbidden in I(h) symmetry. The high-frequency C60 modes are shifted to slightly lower frequency, indicating a weakening of the C-C bonds. This is thought to arise from metal to C60 pi-backbonding.
