Abstract
Three iso-quinolinium ylids are studied by visible electron absorption spectroscopy from the point of view of their interactions with solvent molecules. The quantum mechanical calculations with Spartan 14 Program and solvatochromism of the intramolecular charge transfer visible absorption band of the studied molecules emphasized the prevalence of universal orientation-induction interactions in aprotic solvents and additionally the presence of hydrogen bond between the ylid molecules and the hydroxyl groups of the solvent molecules. The contribution of each type of interactions in the studied solutions is finally established by a multilinear regression applied to solvatochromic data.
