The phenomenon of Raman scattering of light was first postulated by Smekai in 1923 and first observed experimentally in 1928 by Raman and Krishnan. Raman scattering is most easily seen as the change in frequency for a small percentage of the intensity in a monochromatic beam as the result of coupling between …

"Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is both an exchange of energy and a change in the light's direction. Typically this effect involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to … See more The elastic light scattering phenomena called Rayleigh scattering, in which light retains its energy, was described in the 19th century. The intensity of Rayleigh scattering is about 10 to 10 compared to the intensity of the … See more The Raman-scattering process as described above takes place spontaneously; i.e., in random time intervals, one of the … See more Raman spectroscopy employs the Raman effect for substances analysis. The spectrum of the Raman-scattered light depends on the … See more • Brillouin scattering • Coherent anti-Stokes Raman spectroscopy (CARS) • Coherent Raman Scattering Microscopy (CRS) • Depolarization ratio See more Modern Raman spectroscopy nearly always involves the use of lasers as an exciting light source.
