Abstract
The atoms or molecules intercalated in a graphite intercalation compound are correlated spatially among themselves, resulting in a static structure factor with sharp peaks. Graphite phonons with momenta corresponding to these structure factor peaks have a higher probability of being scattered into the Brillouin zone center and becoming Raman active. With this momentum selection scheme, we can interpret the observed Raman features of graphite intercalation compounds with various in-plane structures.
