Raman spectroscopy is an inelastic scattering phenomenon the probes molecular vibrations to provide a molecular fingerprint of materials. Currently, there are six major types of Raman spectroscopy in use today, which are: Spontaneous Raman Spectroscopy, Resonance Raman spectroscopy (RRS), Surface Enhanced Raman spectroscopy (SERS), Coherent Anti-Stokes Raman Scattering (CARS), Stimulated Raman Spectroscopy (SRS) and Spatially Offset Raman Spectroscopy (SORS).
