Abstract

Two limiting values for the first hyperpolarizability of three benzoic and three cinnamic acids in water, have been determined by the hyper-Rayleigh scattering technique at 1064 nm. The basic form of these organic acids has a higher value of molecular hyperpolarizability (β_b) than the corresponding acidic form (β_a). This is also confirmed by quantum chemical calculations.
