Dynamic light scattering experiments
WebSep 22, 2024 · This well established principle is used in dynamic light scattering (DLS), or also called photon-correlation spectroscopy, which is a widely popular and highly adaptable analytical method applied in different fields of life and material sciences, as well as in industrial quality control processes. WebThe light scattering: ccording to the semi-classical light scattering theory [Berne and Pecora, "Dynamic Light scattering" John Wiley, 1975], when light impinges on matter, the electric field of the light induces an oscillating polarization of electrons in the molecules. Hence the molecules provide a secondary source of light and
