WebbRaman scattering is the scattering of photons by excited molecules at higher energy levels. It is otherwise called the Raman effect. The kinetic energy of the incident particle is increased or decreased and is constituted by Stokes and anti-Stokes portions, where photons are inelastically scattered. WebbA Raman spectrum is a powerful tool for materials research, the development of new pharmaceuticals and wherever chemical microanalyses down to the nanometer range …
WebbRaman. The Raman effect is weak (often referred to as a one in ten million event), resulting from an energy event when photons of monochromatic light (laser) interact with a molecule that leads to a release of inelastic photons. WebbExperts define Raman scattering as the scattering of photons by the molecules whose excitement takes place to the higher energy levels. Experts also call it the Raman Effect. Moreover, inelastic scattering of the photons takes place, which means that an incident particle’s kinetic energy is either lost or increased and comprises of Stokes and ...
