Definition

Raman spectroscopy is a spectroscopic technique based on the inelastic scattering of photons (the Raman effect ), resulting in a shift of the frequency of the monochromatic light used for irradiating the sample, based on molecular vibrations and rotations (or other low frequency movement modes in a system). Microspectroscopy refers to spectroscopy performed in a spatially resolved manner.

Basic Principles and History

The inelastic scattering of photons has been postulated on theoretical grounds at the area of quantum mechanics (Smekal 1923) and was experimentally demonstrated shortly after in liquids (Raman and Krishnan 1928) and in crystals (Landsberg and Mandelstam 1928). This inelastic scattering (the Raman effect) is the basis of Raman spectroscopic methods that study molecular vibrations and rotations. In many sense, Raman spectroscopy is complementary to...
