A detailed lineshape analysis shows that the bands associated with the nanotube radial breathing mode are composed of a sum of individual peaks whose relative intensities depend strongly on the laser energy, in agreement with prior work. On the other hand, the shape of the Raman bands associated with the tangential C-C stretching motions in the 1500-1600 cm−1 range does not depend significantly on the laser energy for laser excitation energies in the ranges 0.94-1.59 eV and 2.41-3.05 eV. However, new C-C stretching modes are observed in the spectra collected using laser excitations with energies close to 1.9 eV. The new results are discussed in terms of the difference between the 1D electronic density of states for the semiconducting and metallic carbon nanotubes.
