Sir CV Raman and Raman Effect Rayleigh had already established the phenomenon of the scattering of light and had provided reasons for the blue colour of the sky. Molecular Scattering of Light When light is scattered by a molecule, the oscillating electromagnetic field of a photon induces a polarisation of the molecular electron cloud, which leaves the molecule in a higher energy state after the energy of the photon is transferred to the molecule.

This is sometimes referred to as the virtual state of the molecule and can be thought of as the formation of a very brief-lived complex between the photon and molecule. The virtual state is unstable and the photon is reemitted almost immediately, as scattered light. The wavelength of the scattered photon is equal to that of the incident photon in the vast majority of scattering events because the energy of the molecule remains constant following its interaction with the photon.

This is the main process and is known as elastic energy of a scattering particle is conserved or Rayleigh scattering. This phenomenon is called the Raman Effect. They found that there is a shift in the energy of the scattered photons light particles - either energy absorption called Stokes scatteringresulting in a redshift, or energy release called a nti-Stokes scatteringresulting in a blue shift.

Importance of the Raman Effect Although termed a very weak effect, as only one scattered particle out of a million undergoes the shift in wavelength, the Raman Effect has proved to be a significant achievement in physics due to its various applications. Nature of light: The Raman Effect further cemented the particle theory of light, which holds that light is composed of tiny particles known as photons.

Proof of quantum theory: The study of the phenomenon of light scattering is one of the most convincing proofs of quantum theory. Applications: The Raman Effect scattering provides information on vibrational, rotational and low-frequency modes of energy of molecules, which are the basis of its numerous applications. Raman Spectroscopy Raman spectroscopy is an analytical technique where scattered light is used to measure the vibrational energy modes of a sample.

Raman spectroscopy provides chemical as well as structural information of molecules. Raman spectroscopy extracts this information through the detection of Raman scattering from the sample. Aloysius Anglo-Indian High School. His father was a lecturer in Physics and Mathematics. He passed his matriculation examination when he was eleven years old and passed his F.

In he joined the Presidency College at Chennai and gained his B. He got gold medal in physics. He finished his M. He attended Financial Civil Service examination and stood first in that. He joined the Indian Association for the Cultivation of Science and became its honorary secretary.
