Chapter 12: Infrared Spectroscopy
IR is a method useful in determining the functional groups of a molecule.
IR radiation causes bonds in a molecule to absorb energy and leads to vibrational excitation, such as bonds stretching and bending. Different types of bond will absorb a characteristic frequency which will allow us to determine which types of bonds are present in a molecule we are working with.
