<div>Raman spectroscopy depends on inelastic scattering of photons, known as</div><div>Raman scattering. It uses monochromatic light using a laser and determines vibrational</div><div>modes of molecules. This technique is commonly used for the identification of</div><div>molecules by providing its structural fingerprint. Due to very low inelastic scattering,</div><div>however, signals obtained by Raman spectroscopy are inherently weak and the problem</div><div>is more with visible light. These weak Raman signals can be used by amplifying them</div><div>by the method known as surface enhanced Raman spectroscopy (SERS). SERS is a</div><div>powerful vibrational spectroscopy technique that allows for highly sensitive structural</div><div>detection of low concentration analytes. The current chapter summarizes the basics of</div><div>Raman spectroscopy and SERS, instrumentation, mechanisms differences and</div><div>applications.</div>
