List three structural features and corresponding absorption ranges (cm−1) that can be used to identify phenytoin by IR spectroscopy. WebInfra red (IR) spectroscopy deals with the interaction between a molecule and radiation from the IR region of the EM spectrum (IR region = 4000 - 400 cm-1). The cm-1 unit is the wave number scale and is given by 1 / (wavelength in cm). IR radiation causes the excitation of the vibrations of covalent bonds within that molecule.
