Overview of Raman Spectroscopy: Fundamental to Applications

Raman spectroscopy is the versatile technique for the characterization of materials in numerous fields of research, not only limited to the science and technology but also expanded towards the archeological, food, forensic analysis, and biomedical applications. The present chapter depicts the journey of the discovery of the Raman effect for growing the interest of the reader for Raman spectroscopy. Further, we discussed the fundamentals including the classical and quantum theory, which was followed by the instrumentation of Raman spectroscopy and an overview of the applications in diverse fields of research. We believe that this chapter leads to an increase in the knowledge and recent advances in the application of Raman spectroscopy.
