Abstract: A linear solvation energy relationship (LSER) was established between the energy in the maximum of the intramolecular charge transfer (ICT) absorption band of p-phenyl-pyridazinium-acetylbenzoyl methylid in binary solutions and Kamlet and Taft solvent empirical parameters. The Hildebrand’s solubility parameter values, H , can be used to estimate the solubility of non-electrolytes in organic solvents, 2H was used as a measure of the enthalpy. The supply of universal and specific solute-solvent interactions as well as the supply of solvent-solvent interactions to the total spectral shifts was calculated.

Keywords: intramolecular charge transfer (ICT), p-phenylpyridazinium- acetyl-benzoyl methylid, Hildebrand’s solubility parameter, LSER.
