In 1923 A. Smekal predicted from theoretical considerations that if a sample was irradiated with monochromatic light energy E=hνo some of this radiation will be inelastically scattered. Inelastic scattering is a process whereby a photon collides with a molecule and is absorbed. However, in a very short time later part of the colliding photon's energy will be emitted by the molecule. The remaining energy corresponds to a change in vibrational quantum state.
In 1928 Chandrasekhara V. Raman, an Indian physicist, observed this effect and later in 1930 he received a Nobel Prize for his work studying the effect which bears his name, the Raman Effect.
As a senior project the design and building was built a study of some simple compounds and the theoretical basis of the Raman effect was proposed.
