Streszczenie

Semi-empirical calculations were carried out on four isomers: 2,4′-, 3,4′-, 2,3′-, and 3,3′-dipyridyl ethylenes (DPE). The energy barriers for internal rotation were obtained using the PM3 Hamiltonian. The Goulon-Rivail and Williams theory were used to describe the dielectric relaxation of these molecules. It was found that steric hindrance should be taken into account for complete analyses of the dielectric responses of these molecules.
