Raman Spectroscopy

This resource is a video guide, which shows how to measure Raman spectra of a powder with the help of Avalon RamanStation (class 1 laser). Raman spectroscopy is an analytical technique which is used to study vibrational, rotational and other low frequency modes in a sample. It relies on inelastic scattering (Raman scattering) of monochromatic light, ususally from a laser, in the visible, near infrared or near ultraviolet range. The laser interacts with molecular vibrations, phonons or other excitations in the system, resulting in the energy of the laser phonons being shifted up or down. The shift energy provides information about the phonon modes in the system. Courtesy of Dr Adrian Boyd, Alan Barclay and Balal Tariq from NIBEC, University of Ulster.
