Raman spectroscopy (named after Indian physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. Raman spectroscopy is commonly used in chemistry to provide a … See more The magnitude of the Raman effect correlates with polarizability of the electrons in a molecule. It is a form of inelastic light scattering, where a photon excites the sample. This excitation puts the molecule into a See more Raman shifts are typically reported in wavenumbers, which have units of inverse length, as this value is directly related to energy. In order to … See more Raman spectroscopy is used in chemistry to identify molecules and study chemical bonding and intramolecular bonds. Because vibrational frequencies are specific to a molecule's chemical bonds and symmetry (the fingerprint region of organic molecules is … See more Raman scattering is polarization sensitive and can provide detailed information on symmetry of Raman active modes. While conventional Raman … See more Although the inelastic scattering of light was predicted by Adolf Smekal in 1923, it was not observed in practice until 1928. The Raman effect was named after one of its discoverers, the … See more Modern Raman spectroscopy nearly always involves the use of lasers as excitation light sources. Because lasers were not available until more than three decades after the … See more Raman spectroscopy offers several advantages for microscopic analysis. Since it is a light scattering technique, specimens do not need to be fixed or sectioned. Raman … See more WebFull spectrum fitting is the most appropriate gamma ray spectral analysis technique for BECA, given the limited energy resolution of the CeBr GRS. Rather than measuring the counts in individual gamma ray spectral lines, a weighted least squares fit is performed on the 0.7 - 10 MeV gamma ray spectrum as a whole on that note entertainment
