| Abstract: | Laser Raman spectroscopy has been applied to the study of various carbons ranging from highly graphitized to amorphous materials. A calculation is presented for such materials based on the assumption of short correlation lengths for normal modes that break the wave-vector selection rules. This calculation leads to expressions for the first-order Raman scattering intensity in terms of the vibrational density of states of a single graphite layer weighted by the electron-phonon couping of the modes to the electromagnetic radiation. |
