Solvent Effect on Ion-associate/Benzenoid species of Azine Dye

The study of dyes, particularly, the color-structure relationships drew from structural and physical organic chemistry, including resonance theory, MO methods and electronic spectra get tremendous momentum. Later on, many research activities have been put forward in the literature concerning the effect of solvent polarity on the formation of adduct of different dyes. These investigations provide distinct information to account the effect of solvent polarity. In this event, the solvent dependent properties are subjected to rigorous mathematical analysis, which rationalize solvent effects in terms of the properties of the medium.
