Abstract :
Many organic compounds exhibit characteristic absorption features in the terahertz (THz) frequency range. Yet, the precise origin of these features is still, in most cases, unknown. This paper shows how solid-state density functional theory can be used to understand the origin of THz spectra in organic crystals, and calculate the THz active normal modes.
