Webb2 aug. 2024 · Raman spectroscopy is a fast and nondestructive characterization technique, which has been widely used for the characterization of the composition and structure … WebbRaman scattering,commonly referred to as the Raman effect, is a two-photon event involving a change in polarizability of the molecule with respect to its vibrational motion in the form of scattered energy.. When light from a laser (single frequency) contacts a sample, it changes the polarization of the molecule's electron cloud, leaving the …
