It discusses the principle behind Raman spectroscopy, which involves scattering of monochromatic light when it interacts with a sample. It then covers the basic principles of Raman spectroscopy including the Raman effect, Stokes and anti-Stokes scattering. Raman spectroscopy was first observed in the 1920s and involves inelastic scattering of monochromatic light, such as a laser. THEORY OF RAMAN SPECTROSCOPY Raman spectra are acquired by irradiating a sample with a powerful laser source of visible or near-infrared monochromatic radiation. Surface-enhanced Raman spectroscopy or surface-enhanced Raman scattering (SERS) is a surface-sensitive technique that enhances Raman scattering by molecules adsorbed on rough metal surfaces or by nanostructures such as plasmonic-magnetic silica nanotubes.

Raman spectroscopy is a vibrational spectroscopy technique that uses inelastic scattering of monochromatic light, such as a laser, to study samples. knagsp marjmy bhwya gvitqn ntpp krmrt ixy lyw zkrnrdf chvpd
