What is the basic concept of Raman effect
Answers
Answer:
Raman effect change in the wavelength of light that occurs when a light beam is deflected by molecules.
Explanation:
when a beam of light transverses a dust free, transparent sample of chemical compound,a small fraction of the light emerges in directions other than that of the incident or incoming beam.
Raman is a spectroscopic technique used to observe vibrational, rotational, and other low-frequency modes in a system. Raman spectroscopy is commonly used in chemistry to provide a structural fingerprint by which molecules can be identified.
A vibrational mode that changes molecular polarizability (dipole moment induced by electric field) results in a change of incident photon energy. As a result, scattered photons will have less energy (Stokes Raman) compared to the incident photon.
