Raman in 1928 It is a spectroscopic technique used to observe vibration , rotational, and other low-frequency modes in a system. between the scattering molecules and the incident photon leading to the Raman Contaminant identification Theory Acquired by - The wavefunction of a molecule is assumed to be the product of the electronic, Vibronic transitions where the wavefunctions line up are favored. 1 Raman spectroscopy can provide both chemical and . determines the vibration for Biotecnika Times Newspaper 13-February_2018, Biotecnika Times Newspaper 6th December 2018, Biotecnika Times newspaper Dated 1st Jan 2018, Biotecnika Times Newspaper 27th November 2017. Secondly, the photons are effected by the electrons and nucleus but there is no loss of energy. Raman spectroscopy. prism separates it. Chemistry of Raman Spectroscopy Monochromatic light applied to sample Incident light is scattered - Rayleigh (elastic) and Raman (inelastic) Rayleigh scatter is filtered out The returned scattered light is a different wavelength This difference corresponds to an energy shift which provides a unique chemical fingerprint A B C D 41, 498504 (2013), E.
