In one version of this effect, allowing higher order mutipole transitions diminishes its energy. When it emits energy proportional to 3 times the incident frequency plus or minus the frequency of a transition, it's called "hyper." Techniques based on this effect include a spatially-offset method, and another method involves adsorbing molecules to a rough metal and is enhanced by incident radiation hitting plasmons. Only molecules which undergo a change in polarization via this effect are visible in its namesake form of spectroscopy, which often employs a continuous-wave laser. Emission occurs when the molecule either has a net gain or loss in energy, giving the Stokes and anti-Stokes lines. For 10 points, name this inelastic scattering of light by a molecule, named for an Indian physicist.
