WebThe absorption bands in IR spectra have different intensities that can usually be referred to as strong (s), medium (m), weak (w), broad and sharp. The intensity of an absorption band depends on the polarity of the bond, and a bond with higher polarity will show a more intense absorption band. WebThe IR spectra for the major classes of organic molecules are shown and discussed. One of the most common applications of infrared spectroscopy is the identification of organic …
