Abstract

The second order Raman spectrum of graphite is shown to exhibit an anomolously sharp feature at an energy higher than twice the energy of the first order Raman line. This feature is compared to the 2667 cm-1 band in the second order Raman spectrum of diamond and is discussed in terms of a two-phonon bound state and ordinary overtone scattering. Also this feature serves to discriminate between current lattice dynamics calculations of graphite.
