The disorder-induced D-band and some other non-zone center Raman modes
of graphite and single wall carbon nanotubes are assigned to phonon
modes in their respective Brillouin zones. In disordered graphite, the
weak, dispersive phonon modes, which have been known but never assigned
so far, are well described by the double resonance Raman process. All
weak Raman peaks observed for sp(2) carbons are useful for determining
the phonon dispersion relations of graphite. In carbon nanotubes, all
semiconducting nanotubes and some metallic nanotubes have van Hove
singular k points for their electronic and phonon energy dispersion
curves at the F point of the Brillouin zone. A corresponding Raman
process is relevant to explain the observed D-band and intermediate
frequency spectra. (C) 2002 Elsevier Science B.V. All rights reserved.
