One of the most widely and commonly used spectroscopic techniques is Infrared Spectroscopy. The absorbing groups in the infrared region absorb within a certain wavelength region. When this absorption is compared with other regions like ultraviolet and other visible regions the absorption peaks are usually sharper in Infrared Spectroscopy. By this, we can say the Infrared (IR) Spectroscopy is very sensitive to determine the functional groups within the sample with different functional group absorb a different particular frequency of IR radiation. Every molecule, characteristic spectrum often referred to as the fingerprint, it can identify by comparing its absorption peak with the data bank of spectra. Infrared Spectroscopy is playing a vital role in the identification and structural analysis of different types of substances, of both organic and inorganic compounds and also used in the qualitative and quantitative analysis of complex mixtures of similar compounds.
