Hyper Rayleigh Scattering (aka Harmonic Light Scattering) is one method for measuring β.

Overview

The Hyper Rayleigh Scattering - Test best schematic

An incident laser generates a second harmonic signal, specifically the frequency double signal. This can be related to the beta of the sample using this formula:

<math>\frac {I_{sample}} {I_{solvent}} = \frac {N_{sample} \langle \beta^2 _{sample} \rangle + N_{solvent} \langle \beta^2_{solvent}\rangle} {N_{solvent} \langle \beta^2_{solvent}\rangle}\,\!</math>
