What is Raman Spectroscopy?
  • Raman spectroscopy depends on a change in the induced dipole moment or polarization to produce Raman scattering
  • When a beam of photons strikes a molecule, the photons are scattered elastically (Rayleigh scattering) and inelastically (Raman scattering) generating Stoke's and anti-Stokes lines.
Advantages of Raman Spectroscopy
  • Because Raman spectroscopy is a scattering process, samples of any size or shape can be examined.
  • Very small amounts of material can be studied down to microscopic levels - 10 microns.
  • Fiber optics can be used for remote sensing.
  • Aqueous samples can be studied.
  • The region from 80-500 cm-1 can be studied with no changes on the same instrument.
