25 February 1993 Measurements of molecular hyperpolarizabilities using hyper-Rayleigh scattering
Author Affiliations +
In this paper we show that Hyper-Rayleigh Scattering (HRS) yields hyperpolarizabilities of organic molecules in solution which are consistent with EFISHG-data. For molecules where dipole moment and (beta) are non-collinear marked differences are noted. We show also the applicability of HRS to obtain (beta) -values for ionic and octopolar compounds. Information obtained from depolarization studies is discussed and preliminary results on dispersion are presented.
