National Science Day 2023 is just around the corner, and this year, we’re celebrating the groundbreaking discovery of The Raman Effect by Indian physicist CV Raman. In 1930, Raman won the Nobel Prize in Physics for his discovery, which revolutionized the way scientists analyze the molecular structure of materials.

Sir CV Raman

What is The Raman Effect?

The Raman Effect is a phenomenon where light is scattered by matter, resulting in a shift in its wavelength. When a beam of light passes through a material, some of the light is absorbed by the molecules, causing them to vibrate.

As a result of this vibration, the light that is scattered has a slightly different wavelength than the original beam of light. This shift in wavelength can provide valuable information about the molecular structure of the material.

Impact of The Raman Effect:

CV Raman’s discovery of The Raman Effect has had a profound impact on various fields of science. It has been used to study the properties of materials such as diamonds, polymers, and biological tissues. The Raman spectroscopy technique, which is based on The Raman Effect, is widely used in chemical and biological research.

The technique is also used in pharmaceuticals to study the structure of drugs and in the field of forensics to analyze trace evidence.
