摘要: Abstract The electronic charge transfer transition of crystalline paranitroaniline has been studied as an example directional dispersion exciton energy levels. It is shown that the factor group splittings observed from four different crystal faces can be unambiguously characterized by dipole-dipole interactions with wavevector direction. energies calculated allowing possibility a more detailed analysis role exciton-phonon coupling in absorption band profiles this system.
