UV visible spectroscopic study of solvation of 2,6-diphenyl-4(2,4,6-triphenyl-1-pyridino)phenolate in ternary solvent mixtures
A new method for analyzing the cybotactic zone in a ternary solvent system by means of electronic absorption spectroscopy has been presented. The position of the intramolecular charge transfer absorption band of 2,6-diphenyl-4(2,4,6-triphenyl-1-pyridino) phenolate has been monitored in four ternary solvent mixtures in which one of the pairs are partially miscible. Investigations have been done in the completely miscible region of the ternary mixtures including the binodal curve. Results have been explained by extending the existing models of solvation in binary solvent mixtures to ternary systems.
