Raman Spectrometer

Raman spectroscopy is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes from molecules. It relies on inelastic scattering, or Raman scattering, of laser light. The laser light interacts with molecular vibrations, phonons or other excitations in the system, and the returned/scattered signal thus has a different frequency than that of the laser. The shift in energy gives information about the vibrational modes in the system. Infrared spectroscopy yields similar but complementary information.
