Raman scattering from the molecular charge transfer crystal anthracene-PMDA
Abstract
The Raman spectrum of the mixed stack charge transfer (CT) crystal anthracene-PMDA, has been measured in the wavelength region near the lowest CT transition at 5458 Å. Six low frequency modes are observed below 140 cm-1, the mode at 130 cm-1 showing strong resonance enhancement. These modes are assigned as librational motion of the anthracene and PMDA molecules by rigid body analysis of X-ray structural data. © 1979.
