Abstract

Abstract A theoretical analysis is presented of an asymmetric broad line shape at ≈ 1500 cm −1 in the observed Raman spectrum of C 8K. The anomalous line-shape is attributable to the coupled excitations of symmetry-allowed phonons and electrons. The electron-phonon coupling strength relevant to the Raman scattering under consideration is also estimated.
