dc.description.abstractSolvent effects on the vibrational and electronic absorption band of different compounds were determined. In increasing the polarity of the solvent a shift of the absorption maxima to lower energy was observed in all compounds. The solvation dielectric constant of dioxane was empirically determined from correlation plot of Lippert-Mataga polarity function versus vibrational absorption maxima of picolinamide and other amides (Acrylamide, propylamide etc.). From linear fit the value of solvation dielectric constant of dioxane was goes to infinite (r,solv=  ), which is unrealistic and unphysical. In addition, from correlation plot of Lippert-Mataga polarity function versus electronic absorption maxima of DMABA, BBA and NBA the value of solvation dielectric constant of dioxane was found to be 3.4, 3.8 and 7.7, respectively. These values were inconsistent and there is no universal solvation dielectric constant from electronic spectroscopyen_US
