Concept introduction:
IR spectroscopy enables us to identify different functional groups in the molecule.
One of the greatest advantages of IR spectroscopy is that the frequency of a particular type of vibration is typically found within a characteristic range of frequencies regardless of the functional group with which the vibration is associated. The fact that absorptions by certain vibrations appear with characteristic frequency ranges enables us to use IR spectroscopy to obtain structural information about a molecule. The absorption peak intensities are based on the oscillating dipole moment. If a particular vibrational mode causes oscillations in the molecule’s dipole moment, a photon is more likely to be absorbed which enhances the absorption intensity.
