This technique is widely used for label-free visualization of lipidic cellular structures in an eponymous "coherent" type of microscopy. The formation of a charge-transfer complex between analyte molecules and silver nanoparticles is one mechanism of signal enhancement in a surface-enhanced version of this technique. The intensity of the signal of this technique is proportional to the square of the electric dipole moment, or the polarizability times the electric field. Performing this technique requires "notch filters" to cut off signals from Rayleigh scattering. The signals from this technique represent either a loss or gain of energy after an inelastic collision with a photon. It is most useful for analyzing symmetrical vibrations of nonpolar groups, unlike IR spectroscopy. For 10 points, name this technique that produces "Stokes" and "anti-Stokes" frequencies and which measures the shape of a molecule using a type of scattering named for an Indian physicist.
