Stokes-Raman Scattering

Discovered by: C. V. Raman, awarded the 1930 Nobel Prize for Physics.

What is it? The inelastic scattering of photons by matter, meaning that there is an exchange of energy and a change in the light's direction.

Why is it important? The effect is exploited by chemists and physicists to gain information about materials for a variety of purposes by performing various forms of Raman spectroscopy.
