Abstract :
Hyper-Rayleigh scattering (HRS) or second harmonic light scattering has become an important method for measuring first hyperpolarizabilities β of organic chromophores. HRS is more flexible and simpler than electric field induced second harmonic generation, which is the principal alternative method for determining β. The motivation for the present work is threefold: (1) to develop reference standards for HRS measurements (2) to test ab initio calculations of hyperpolarizabilities, and (3) to understand the effects of intermolecular interactions on nonlinear optical properties and measurements
