Webb4 apr. 2024 · The Raman effect involves the scattering phenomenon of light by a system wherein the scattered light contains the wavelength components differing from the wavelength of incident light. The intensities of these components are much lower and depend on the systems' characteristics as well as the intensity of the source itself. http://www-g.eng.cam.ac.uk/nms/publications/pdf/Lazzeri_PRB2006.pdf
