Description 472-481
Different examples of solvatochromic shifts are shown and the theory that explain the non-specific general solvent
effects are discussed here. The use of solvatochromic shifts for the determination of excited state dipole moment has been
presented in detail in connection with a brief overview of different solvent polarity functions. The lack of proper theoretical
expressions to explain the specific solvent effect stimulates to introduce the concept of “empirical measures of solvent
polarity”, based on well known, convenient, solvent sensitive model processes. Various solvent sensitive polarity probes are
discussed in this context. So far as quantitative estimation of various parameters responsible for the observed
solvatochromic shifts are concerned, introduction of multiparameter approaches, its application in recent years has been
carefully analyzed. The review also focuses some of the recent developments on the theoretical calculations of various
solute-solvent interaction parameters based on quantum mechanical approaches. This issue solvation interaction by the use
of mixed solvents has been discussed in detail, starting from the early development of the theories related to preferential
solvation to the recent scenario, with a critical survey on the application of the concept of preferential solvation in the
solubilization of drugs, polymers considering the emerging ‘green approach’ in recent years.
