Raman spectroscopy is a versatile analytical technique that provides detailed molecular information through the inelastic scattering of monochromatic light, usually from a laser. When an incident light interacts with a molecule’s vibrational, rotational, or other low-frequency modes, most of the scattered light remains at the same wavelength (Rayleigh scattering). However, a small fraction is scattered at different wavelengths due to energy exchanges, known as Raman scattering. The resulting spectrum acts as a molecular fingerprint, enabling the identification of compounds and insights into molecular structures, phase transitions, and chemical environments. A key advantage of Raman spectroscopy is its minimal sample preparation and resistance to water interference, making it ideal for studying biological samples, aqueous solutions, and various materials. Its nondestructive nature ensures sample preservation, valuable in the field of forensics. Raman spectroscopy is applicable to gases, liquids, and solids, providing high specificity for molecular identification. Raman Spectroscopy basically examines changes in the polarizability of a chemical bond. Interaction of light with a molecule can cause its electron cloud to distort, and this deformation is known as polarizability change. Raman active modes are generated when polarizability varies due to unique energy transitions that occur in molecular bonds. Widely used across disciplines such as chemistry, biology, materials science, and medical diagnostics, it offers critical insights into molecular structures and compositions.
