Doable resonant Raman scattering in graphite

We find that the electronic dispersion in graphite gives rise to double res onant Raman scattering for excitation energies up to 5 eV. As we show, the curious excitation-energy dependence of the graphite D mode is due to this double resonant process resolving a long-standing problem in the literature and invalidating recent attempts to explain this phenomenon. Our calculati on for the D-mode frequency shift (60 cm(-1)/eV) agrees well with the exper imental value.
