- Raman was now obsessed with the phenomenon of light scattering. His group in Calcutta began an extensive series of measurements of light scattered primarily by liquids but also by some solids. As a result, Raman was able to explain the blue color observed in the ice of Alpine glaciers.

Does Raman scattering reveal the structure of a substance?
In physics, Raman scattering or the Raman effect (/ ˈ r ɑː m ən /) is the inelastic scattering of photons by matter, meaning that there is both an exchange of energy and a change in the light's direction.
A reason why Raman spectroscopy is useful in biological applications is because its results often do not face interference from water molecules, due to the fact that they have permanent dipole moments, and as a result, the Raman scattering cannot be picked up on. This is a large advantage, specifically in biological applications. [31]
Mar 24, 2014 · The wavelength dependence of scattering is a factor of lambda^4, so Martian dust must (blue light wavelength/red light wavelength)^4 = 3^4 = 27 times smaller than scattering particles in Earth’s atmosphere.
Principle of Raman Spectroscopy. Types of Raman Spectroscopy. Applications of Raman Effect. Frequently Asked Questions – FAQs. What is Raman Scattering? Raman scattering is defined as the scattering of photons by excited molecules at higher energy levels. It is also known as the Raman effect.

- When the energy of the scattered photons is more than the incident photon, the scattering is known as anti-stokes scattering.
- It is used to study the vibrational, rotational, and low-frequency modes of the molecules.
- Raman scattering is defined as the scattering of photons by the excited molecules that are at higher energy levels.

The Raman effect, also known as the Raman scattering, is a light scattering that provides remarkable details of the substance that scatters the light. The spectrum that we see as a result of the Raman scattering is a unique fingerprint of that substance.
Mar 1, 2009 · After all, Smekal had provided the theoretical basis for light scattering in 1923, and Landsberg and Mandelstam had simultaneously discovered the Raman effect on solid quartz in 1928. Why was the Nobel given only to Raman? First, Smekal’s work was not widely known at the time that Raman had conducted his scattering experiments.
