Ramanszabály

Ramanszabály, also known as Raman scattering, is a phenomenon in spectroscopy that involves the inelastic scattering of photons by molecules. It was first observed by Indian physicist Sir Chandrasekhara Venkata Raman in 1928, for which he was awarded the Nobel Prize in Physics in 1930. The effect is named after him.

In Raman scattering, a photon interacts with a molecule, causing it to vibrate or rotate. This interaction results in the photon losing or gaining energy, which is then emitted as a new photon with a different wavelength. The difference in energy between the incident and scattered photons corresponds to the energy levels of the molecule's vibrations or rotations.

Raman spectroscopy is a powerful analytical tool used to identify and study the chemical composition and structure of materials. It is particularly useful for studying materials that are difficult to analyze using other techniques, such as liquids, polymers, and biological samples. The technique is non-destructive and can be used to analyze samples in their natural state.

The Raman effect is a fundamental process in the interaction of light with matter and has numerous applications in fields such as chemistry, physics, biology, and materials science. It is also used in various technologies, including optical communication, laser spectroscopy, and medical diagnostics.
