| Popis: | International audience; Hyper Rayleigh Scattering (HRS) is a method allowing the retrieval of metallic nanoparticles morphology. It is usually conducted in a right angle geometry preventing the full determination of all the sample information. To alleviate this problem, we report experiments in this manuscript where we have employed a multi-angle geometry in order to further complement the study. This method is applied to a standard push-pull molecular compound, a well-defined symmetry model system, and then is extended to gold metallic nanoparticles with a diameter of 5 nm. In this way, it is possible to observe how shape deformation, or in other words symmetry, is obtained as compared to the one solely retrieved from the right-angle geometry. |
