Abstract

Possibilities and limitations of second-order nonlinear light scattering techniques in the determination of the components of the molecular hyperpolarizability tensor (beta) _ikl are discussed. The experimental feasibility of such measurements is demonstrated using para- nitroaniline as the nonlinear molecule. The number of independent measurements that can be performed on the hyperpolarizability tensor is limited by the number of rotational invariants of the isotropic orientational average ((beta) _ikl(beta) _jmn). For the cases of general nonlinear light scattering and hyper-Rayleigh scattering the maximum numbers of independent measurements are fifteen and six, respectively.
