Abstract
The hyperpolarizability β of an ionic species, 1-anilinonaphthalene-8-sulfonic acid ammonium salt (ANS), was determined in various solvents by the Hyper-Rayleigh scattering (HRS) technique. Increase in the solvent polarity led to a decrease in the hyperpolarizability; i.e. β=37.4±2.5×10 -30 esu in p-dioxane and β=10.3±1.3×10 -30 esu in water. The solvent effect was explained by considering the dissociation ratio of the sulfonic acid ammonium group in solution, which influences the intramolecular donor–acceptor interaction between phenylamino and sulfonic acid ammonium groups.
