Heller et. al. discovered “transition sliding” when applying this technique to graphene, which is unusually explained by a fourth-order “double resonance” model instead of KHD theory. Calcium fluoride is used as a substrate in a form of confocal microscopy that relies on this technique. George (-5[1])Placzek developed an approximation in this technique that compares the depolarization ratio of a mode to 0.75 to determine its symmetry. A (*) notch filter is used to increase the resolution of this technique. Molecules are adsorbed onto nanostructured gold or silver to enhance their signals in one form of this technique. Molecules with a center of symmetry cannot have modes active in both infrared spectroscopy and this technique. (10[1])For 10 points, (10[1])give this technique that measures Stokes and anti-Stokes shifts caused by (10[1])inelastic scattering of photons and is named after an Indian physicist. ■END■
