Abstract: Hyper-Rayleigh scattering in solution is used for the determination of the hyperpolarizability of non-linear optical molecules. Obtaining the first hyperpolarizability-beta without having to independently determine the dipole moment-mu and the second hyperpolarizability-gamma is an advantage over the electric-field-induced second-harmonic generation technique. Values of the first hyperpolarizability-beta of 23 x 10(-30) esu for para-nitroaniline, 105 X 10(-30) esu for 4-methoxy-4'-nitrostilbene, and 95 x 10(-30) esu for 4-hydroxy-4'-nitrostilbene dissolved in chloroform have been obtained. The equivalent-internal-field model is shown to hold for small saturated molecules.
