Rayleigh and Raman scattering are elastic and inelastic forms of light scattering, usually by molecules. From a common ground in electrodynamic theory, the mechanisms are explained and shown to provide the basis for using Raman effect measurements as a spectroscopic tool.doi:10.1016/B978-0-12-374413-5.00269-4Andrews, DavidEncyclopedia ...
According to the classical theory of electromagnetic radiation, electric and magnetic fields oscillating at a given frequency are able to give out electromagnetic radiation of the same frequency. Electromagnetic radiation theory can explain light scattering phenomena. When deriving the Raman Effect, it is...
Chapter Diffraction and Scattering 5.16.1 Rayleigh Scattering 5.16.1.1 Rayleigh scattering: The basics If the linear dimension of the scatterer is on the order of the wavelength or a fraction thereof, one speaks of Rayleigh scattering since Lord Rayleigh was the first to put forward a theory of...
Rayleigh scattering has been studied in single- and multi-mode optical fibers. And the relevant theories are well established. In particular, with regard to the Rayleigh scattering theory developed for MMFs21, a mode-continuum model was adopted and an incoherent total power transfer formulism was ...
(0.1 to 1 °C)5and remains a rather simple and cheap scheme, compared to other DTSS techniques. However, Rayleigh scatter OFDR has remained quite limited in terms of sensing length (30-100m). For this reason, other methods have been developed such as Raman scattering (ROTDR)6,7, ...

It is convolved with the rotational Raman spectra of O(2) and N(2) to produce an atmospheric Ring effect source spectrum.doi:10.1364/AO.36.005224Chance, Kelly VSpurr, Robert J. DAppl OptChance, K. V. and Spurr, R. J. D.: Ring effect studies: Rayleigh scattering, incl...
For the calculation, we used a finite difference time domain (FDTD) method (PLANC-FDTD Ver.6.2; Information and Mathematical Science Laboratory Inc., Tokyo, Japan). We compared polarization dependencies among the calculated Rayleigh scattering spectra, experimental Rayleigh scattering spectra, and SERS...

This interfacial layer, when illuminated by light, behaves as an optical dipole lattice and contributes an instantaneous near field which enhances the local field on neighboring atoms, molecules, or nanomaterials, which in turn may lead to enhanced Rayleigh scattering, Raman scattering, and ...
