Raman spectroscopy
Ir. Sugeng Endarsiwi ( Printing Ink Manufacturer ) What is Raman spectroscopy? Raman spectroscopy is a chemical analysis technique which involves illuminating a substance with a laser and analyzing the light that is scattered off the surface of the substance. The scattered light can provide a lot of information about the substance and its structure, and can be used to identify, characterize, and quantify many chemical components. Light scattering explained When light is scattered off a sample there are two possible outcomes: (1) Elastic scattering , also known as Rayleigh scattering, occurs when the scattered light has the same energy as the light that initially struck the sample. This means that the elastically scattered light will be the same frequency, wavelength, and color as the original beam of light. (2) Inelastic scattering, or Raman scattering , occurs when the scattered light has a different energy than the light that initially struck the sample. This ...
