    Infrared (IR) spectroscopy

    Absorption of infrared radiation brings about changes in molecular vibrations within molecules and ‘measurements’ of the ways in which bonds vibrate gives rise to infrared spectroscopy. Atom size, bond length and bond strength vary in molecules and so the frequency at which a particular bond absorbs infrared radiation will be different over a range of bonds and modes of vibration.
