Ultraviolet and visible light give rise to electronic excitations.. Spectroscopy of organic molecules is possible because the absorption of radiation is restricted to quanta having energies corresponding to specific molecular excitations:. 11/15 . Lecture.

In the most basic terms, the infrared spectrum is formed as a consequence of the absorption of electromagnetic radiation at frequencies that correlate to the vibration of specific sets of chemical bonds from within a molecule. First, it is important to reflect on the distribution of energy possessed by a molecule at any given moment, defined as the sum of the contributing energy terms:.
