Rayleigh scattering raman scattering
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 exciting source. In 1908, another form of elastic scattering, called Mie scattering was … See more 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 … See more The Raman-scattering process as described above takes place spontaneously; i.e., in random time intervals, one of the many incoming photons is scattered … See more Raman spectroscopy employs the Raman effect for substances analysis. The spectrum of the Raman-scattered light depends on the … See more Modern Raman spectroscopy nearly always involves the use of lasers as an exciting light source. Because lasers were not available until … See more The following focuses on the theory of normal (non-resonant, spontaneous, vibrational) Raman scattering of light by discrete molecules. X-ray Raman spectroscopy is … See more The inverse Raman effect is a form of Raman scattering first noted by W. J. Jones and Boris P. Stoicheff. In some circumstances, Stokes scattering can exceed anti-Stokes scattering; in these cases the continuum (on leaving the material) is … See more • Brillouin scattering • Coherent anti-Stokes Raman spectroscopy (CARS) • Coherent Raman Scattering Microscopy (CRS) See more WebImpact Statement: We proposed a model to analyze the random variation in scattering with time and location. Employing the model, we simulated stochastic scattering in distributed …
