摘要：

We calculate the second order Raman spectra in graphite and compare it to recent measurements on highly oriented pyrolytic graphite (HOPG). Electron-phonon interaction is calculated as the inner product of the amplitude of vibration with the deformation potential vector. The deformation potential vector is calculated by atomic basis functions and the potential fitted by Gaussians. When we include the electron-phonon matrix element, the peak positions and the shapes agree well with the experimental results. The characteristic double peak structure of the G' band in HOPG is reproduced well.
