WebJul 24, 2024 · Infrared spectroscopy is based on molecular vibrations caused by the oscillation of molecular dipoles. Bonds have characteristic vibrations depending on the atoms in the bond, the number of bonds and the orientation of those bonds with respect to the rest of the molecule. WebInfrared spectroscopy is a technique that probes the vibrations within a material. It is complementary to Raman spectroscopy (Section 11.2.2) in that many Raman active vibrational modes are not detectable in infrared spectroscopy and vice versa. It can identify functional groups which have characteristic vibrational energies and can thus be ...
