Abstract
Molecular motions of various solid state organic charge-transfer complexes are investigated using laser Raman spectroscopy. The relative amplitudes of various modes on the donor and the acceptor molecules are studied by isotopic substitutions of the donor and the acceptor. The nature of these motions is analyzed in terms of the giant molecule or the sublattice model. In the giant molecule approach, there is an appreciable amplitude an both the donor and the acceptor molecules; while in the sublattice approach the molecular motions are characterized as either belonging mostly to the donor or to the acceptor. The validity of either model depends on the strength and delocalization of charge-transfer interactions. In addition, the role of donor and acceptor stoichiometry in determining the nature of the molecular motions will be discussed.
