Hint: We know that the principles of Raman spectroscopy have been understood for the past 80 years and are based on the Raman effect, the phenomenon of inelastic scattering of light (Raman scattering), which was discovered by Dr. C.V. Raman in 1928. This occurs because only molecules that are vibrationally excited prior to irradiation can give rise to the anti-Stokes line. Hence, in Raman spectroscopy, only the more intense Stokes line is normally measured - Raman scattering is a relatively weak process. The number of photons Raman scattered is quite small.
Complete step by step answer
The Nobel Prize in Physics 1930 was awarded to Sir Chandrasekhara Venkata Raman for his work on the scattering of light and for the discovery of the effect named after him. February 28, 1928 is recognised as a path-breaking day in the history of Indian Science. It was on this day that CV Raman discovered the Raman Effect based on experiments on the scattering of lights. This invention was of great value since it gave further proof of the quantum nature of light. He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman effect.
Sir C. V. Raman won the Nobel Prize in 1930.
So, the correct answer is option B.
Note: We know that Raman spectroscopy is used in many varied fields – in fact, any application where non-destructive, microscopic, chemical analysis and imaging is required. Whether the goal is qualitative or quantitative data, Raman analysis can provide key information easily and quickly. Raman effect takes place when light enters in a molecule and interacts with the electron density of the chemical bond causing electromagnetic field in the molecule leading to vibrational and deformation of frequency shift. The incident photon excites the electron into a virtual state.
