摘要：
Experimental and theoretical studies of the vibrational modes of carbon nanotubes are reviewed. The closing of a 2D graphene sheet into a tubule is found to lead to several new infrared (IR)- and Raman-active modes. The number of these modes is found to depend on the tubule symmetry and not on the diameter. Their diameter-dependent frequencies are calculated using a zone-folding model. Results of Raman scattering studies on are-derived carbons containing nested or single-wall nanotubes are discussed. They are compared to theory and to that observed for other sp(2) carbons also present in the sample.
