Paper Abstract

The electronic absorption spectra of four carbanion monosubstituted pyridazinium ylids in binary solvents are analyzed in this paper. The binary solvent is made, in different ratios, by two miscible liquids (one active and one inactive from the intermolecular interactions point of view). The composition of the first solvation shell of the studied ylids was established by using the spectral data. The concentration of the active solvent in the first solvation shell is higher than in the rest of the ternary solution. The difference is appreciable especially at low molar concentrations of the active solvent in ternary solutions. The interaction energy in pairs of pyridazinium ylid-active solvent molecules was also estimated in the limits of a cell model of the ternary solution.
