When light interacts with a molecule, most photons are elastically scattered (Rayleigh scattering). A small fraction, however, is inelastically scattered, experiencing a change in energy and ...

Raman spectroscopy is a technique that examines ... most of it bounces unchanged – this is called a Rayleigh scattering. However, a small portion of the light shifts in energy because the ...

In Raman spectroscopy, a sample is typically illuminated by a laser beam, and the scattered radiation is recorded and analyzed. The light scattering observed is classified as either Rayleigh ...

Enhancement techniques including UV resonance Raman, coherent anti-Stokes Raman scattering, surface-enhanced Raman scattering and tip-enhanced Raman spectroscopy overcome the traditional challenge ...
