摘要

The resonance Raman (RR) spectrum of C_70 has been studied in benzene using 11 laser excitation energies across the main visible absorption band (MVAB) of C_70 between 514.5 and 406.7 nm. Raman excitation profiles (REPs) were constructed for the 15 most intense RR bands of C_70 , and symmetry assignments have been made partly on the basis of polarization work. Contrast is made to work performed on thin films where problems have arisen from the symmetry-lowering effect of the surface and from neglect or resonance.
