Fourier Transform Infrared Spectrometer
Vibrating spectroscopy, which has a wide range of applications in academic and industrial laboratories, is divided into two as Raman Spectroscopy and Infrared Spectroscopy. In both methods, it gives descriptive information about the bonds in a molecule or compound structure.
Infrared (IR) Spectroscopy is basically based on the absorption of infrared light by the object under study. Absorption occurs when the required amount of wave energy for vibration and rotation of the bonds in the molecule is sent by the device from the infrared region of the electromagnetic spectrum. Infrared light is absorbed only by molecules with variable dipole moments. (For example, while co-diatoms such as N2, O2 do not give results in FTIR, the FTIR spectrum of HCl can be taken).
Another technique, Raman Spectroscopy, works by inelastic scattering of light by the bonds in the molecule. Raman scattering occurs only with bond polarization that changes during vibration. Therefore, molecules that are not infrared-active show Raman-active properties if they are able to undergo a polarization change. Therefore, these two spectroscopic methods are complementary to each other.
