The molecular structure information of functional group and chemical bond has been provided in IR spectra. In general, a chemical bond may present multiple IR peaks, and one peak may be a superimposed absorption from more than one chemical bonds. It is important to be able to interpret the characteristic peaks from the major functional groups in the compounds.
