Solvent effect on electronic absorption spectra of some chlorophenols: Part II - Application of Bakhshiev's theoretical model for elucidating excited state dipole moments and specific solute-solvent interaction energies

Abstract

A systematic and simple procedure employing Bakhshiev's expression for solvatochromic frequency shifts in electronic absorption spectra for estimating the excited state dipole moments and specific solute-solvent interaction energies is developed. The results for several chlorophenols based on this method are found to be in close agreement with those obtained by applying the more commonly used McRae's expression-for solvent-induced frequency shifts. The method described herein can be employed as an alternative approach for studying solute-solvent interactions.
