Raman Spectroscopy for Analysis and Monitoring. The Raman scattering technique is a vibrational molecular spectroscopy which derives from an inelastic light scattering process. With Raman spectroscopy, a laser photon is scattered by a sample molecule and loses ( or gains) energy during the process.

Why Raman spectroscopy? • Information on rotational and vibrational levels • Raman effect small but accessible by use of lasers • Complementary information to IR spectroscopy phomonuclear diatomic molecules, low frequency range • In situ analysis of organic and inorganic compounds • Analysis of aqueous solutions and solids (powders)

A plot that shows the intensity of scattered radiation as a function of the scattered photon's energy, expressed as a change in the wavenumber, \(\Delta \overline{\nu}\), is called a Raman spectrum and values of \(\Delta \overline{\nu}\) are called Raman shifts.
