Martin Fleischman used pyridine adsorbed on silver which had been electrochemically roughened to develop this phenomenon's surface-enhanced variety, and conjugated molecules with large dipole moments can produce a stronger form of this phenomenon's hyper version. One of the byproducts of its stimulated variety can be amplified to produce a namesake laser. Discovered in crystals by Grigory Landsberg and Leonid Mandelstam, its linearly polarized and circularly polarized radiation is governed by the Stokes parameters. Divided into Stokes and anti-Stokes varieties, FTP, name this inelastic scattering of a photon named for its Indian discoverer.
