The Raman Effect
- About
- CV Raman, a physicist, was awarded the Nobel Prize in 1930 for discovering Raman Effect.
- In addition, it describes the inelastic scattering of light by materials, which causes a shift in the frequency of the scattered light.
- In layman’s terms, it is a change in the wavelength of light caused by molecules deflecting a light beam.
- Furthermore, the Raman effect provides the foundation for Raman spectroscopy.
- Chemists and physicists utilise it to learn about materials.
- Furthermore, spectroscopy studies the interaction between matter and electromagnetic radiation.
