The spectral width, or γ value, of the Raman excitation profile for single-wall carbon nanotubes is calculated by evaluating the lifetime of the carriers. The calculated results for the γ values are compared with the experimental spectral width of the Raman excitation profile. The γ values evaluated by the electron-phonon interaction show a strong chirality and diameter dependence which is crucial for obtaining the peak intensities of the resonance Raman spectra. Moreover, for metallic carbon nanotubes, we expect an additional contribution to the calculated γ values by comparing them with the experimental results. In particular, we expect that the plasmon excitation in metallic carbon nanotubes may also contribute to the spectral linewidth γ.
