Importance of CARS experiment:

The CARS experiment permits the study of the Raman transitions in the presence of incoherent background radiations.

SERS stands for Surface Enhanced Raman Scattering. Some of the applications of a SERS experiment are:

• Analysis of the type (or types) of the ink to decipher the forged handwriting a forensic application
• Determination of the degree of cross-linking in a polymer sample
• Analysis of biological materials in their physiological medium
