Raman effect

The Raman effect occurs when light interacts with a material, such as a molecule, causing some of the light to change in energy and thus in color. This happens because the light's photons transfer energy to or from the molecules' vibrations, leading to a slight shift in the light's wavelength. When scientists analyze these shifts, they can determine the molecular structure and composition of the material. This phenomenon is the basis for Raman spectroscopy, a technique used in chemistry, physics, and medicine for material identification and analysis.
