Abstrakt: Molecular crystal - chloranil systems forming charge transfer complexes were studied in solutions and as melts at precrystallization temperatures. Dielectric permittivity of chloranil mixtures with stilbene, naphthalene and diphenyl was measured as function of concentration and temperature, and absorption spectra of the same systems in CCl 4 solution were analyzed. The results obtained suggest the presence of additional molecular ordering in the melts at chloranil concentrations 0,5-5 mol.%. A model of such ordering accounting for both specific and non-specific intermolecular interactions is proposed. [ABSTRACT FROM PUBLISHER]
