Suppression of Multiphoton Fluorescence in Hyper-Rayleigh Scattering

Hyper-Rayleigh scattering (HRS) has become widely accepted as an experimental technique for the determination of the first hyperpolarizability (second-order nonlinear polarizability), β, of molecules in solution. Apart from being simpler both theoretically and experimentally than electric-field-induced second-harmonic generation (EFISHG)—applicable to neutral, dipolar molecules only—HRS is the sole technique that gives a β value for ionic or octopolar species. The combination of HRS and EFISHG also allows different elements of the hyperpolarizability tensor to be analyzed.
