The double resonance Raman spectra of the disorder-induced D-band and some other non-zone-center phonon modes are discussed for two-dimensional (2D) graphite and to some extent for single wall carbon nanotubes (SWNTs). The phonon dispersion relations of graphite can be determined using Raman spectroscopy by measuring the non-zone center Raman phonon frequencies in combination with theoretically determined phonon q-vectors. We report a fit of the phonon dispersion relations to experimental Raman spectra which were previously observed but have not yet been assigned to specific phonon branches. We found that the D-band and the G′-band of 2D graphite consist of, respectively, two and one Raman Lorentzian peaks, while 3D graphite shows two G′-band Lorentzian peaks. The appearance of two G′ peaks in the resonance Raman spectra of SWNTs may come from resonances of one laser line with two different van Hove singularities.
