Detection of buried microstructures by nonlinear light scattering spectroscopy
Many processes in chemistry and physics rely on the structure, growth or change of material buried in solids. The impenetrable surrounding medium often prohibits the study of such material in situ. Nonlinear light scattering can be used to observe the internal structure of a crystalline state embedded inside another solid state. Vibrational sum frequency scattering patterns of polymer microspheres, consisting of both amorphous and crystalline material, reveal the size of the buried microstructure and the optical components of the second-order susceptibility of the material. The vibrational spectra reveal the molecular structure.
