Abstract in English
In this paper, an optical setup to produce harmonic hyper-Rayleigh light
scattering (HRS) from organic molecules in solution has been built up. In
principle, HRS measures contribution coefficients of dipole and octupole parts.
The nonlinear susceptibility of the second order of six organic molecules in
solution from different chemical components such as Pyridinium, Quinolinium
groups and organic Borone complexes has been determined. The nonlinear
susceptibility measurements help to discover and select the most efficient
molecules which can be used later as polymer matrices.
