WebThis phenomenon is termed a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light. Shorter wavelength and high-frequency scatter more due to the waviness … 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 … See more Raman spectroscopy employs the Raman effect for substances analysis. The spectrum of the Raman-scattered light depends on the molecular constituents present and their … 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.
