Spectroscopy Raman and IR Spectroscopy

Presentations | English

Raman and Infrared (IR) spectroscopy involve the study of the interaction of radiation with molecular vibrations but differ in the manner in which photon energy is transferred to the molecule by changing its vibrational state. Raman spectroscopy depends on a change in polarizability of a molecule, whereas IR spectroscopy depends on a change in the dipole moment. Raman spectroscopy measures relative frequencies at which a sample scatters radiation, unlike IR spectroscopy which measures absolute frequencies at which a sample absorbs radiation. The fundamental principles that govern each is that: the Raman effect is weak, resulting from an inelastic raman scattering process that occurs when light interacts with molecules whereas the IR spectroscopy is a stronger technique that relies on absorption of light by molecules.
