The Raman phenomeno n The Raman sp ectroscop y measures the vibrational motions of a molecule lik e infra- red sp ectroscop y. As the name suggests, this phenomenon is named after Sir C. V. Raman. Raman spectroscopy, a molecular spectroscopy which is observed as inelastically scattered light, allows for the interrogation and identification of vibrational (phonon) states of molecules. In addition, Raman spectroscopy has been successfully applied to the analysis of gunshot and explosive residues, geological samples, fibres and various bodily fluids. Raman spectroscopy: complimentary to IR spectroscopy. Principle about the RS and IR can be found at Chemwiki Infrared Theory and Raman Theory. Selection Rules 11 - THEORY OF RAMAN SPECTROSCOPY Raman spectra are acquired by irradiating a sample with a powerful laser source of visible or near-infrared monochromatic radiation. Spectra are scaled and shifted for clarity. It is a good idea to check an "easy" spectrum such as chloroform often. Raman spectroscopy is a spectroscopic technique that makes use of Raman scattering or inelastic scattering of monochromatic laser light, and it is used to study the rotational, vibrational, and other modes of a system. 2. Raman spectroscopy is a form of vibrational spectroscopy, much like infrared (IR) spectroscopy. If you continue browsing the site, you agree to the use of cookies on this website.
