Abstract

Two spectrally active molecules - carbanion monosubstituted cycloimmonium ylids having as heterocycles benzo-[f]- quinolinium and p-phenyl-pyridazinium - can offer information about the local field of forces in binary solutions. Hyper Chem. 8.0.6 software was used to characterize these molecules from the structural, energetic and electro-optical point of view. The visible band of the cycloimmonium ylids appears by an intramolecular charge transfer (ICT) from the carbanion to the heterocycle. It is very sensitive to the solvent nature. The projection of the excited state dipole moment on the dipole moment in the electronic ground state was obtained for two studied ylids on the basis of the existent theories regarding the intermolecular interactions in liquid phase studied by spectral means.
