Raman Spectroscopy - Chemistry

Raman Spectroscopy Raman Spectroscopy has become an incredibly useful analytical technique for the identification of organic, inorganic, and biological samples. Raman spectra can generally be measured from solids, liquids, and gases, including thin films and powders. Material characterization Pharmaceutical analysis Disease diagnostics Forensics Process control Granger et. new textbook Raman Spectroscopy It is the shift in wavelength of the inelastically scattered radiation that provides the chemical and structural information. Raman shifted photons can be of either higher or lower energy, depending upon the vibrational state of the molecule under study.

Raman Spectroscopy Rayleigh and Raman scattering (Stokes and anti-Stokes) as seen on energy level diagram. An associated spectrum is included, note the Raman lines intensity are greatly exaggerated. Raman spectra are usually shown in wavenumbers as a shift from the Rayleigh scattered line.

Advantage of Raman Effects • (1). Raman Spectroscopy can be used not only for gases but also for liquids & solids for which the infrared spectra are so diffuse as to be of little quantitative value. • (2). Raman Effect is exhibited not only by polar molecules but also by non-polar molecules such as O2, N2, Cl2 etc. • (3).
