WebInfrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify … WebInfrared Spectroscopy: Vibration of organic compounds. A pair of atoms constantly vibrates. When the organic molecules absorb infrared radiation, the bonds between the different atoms vibrate even more. Due to this, the covalent bonds in the molecule also vibrate and are forced to either stretch, bend, or twist.
