HO. O. A technique that is very frequently used toist in the identification of unknown compounds uses infrared IR light, a form of electromagnetic radiation..Objective. To learn various functional groups encountered in Organic Chemistry. To learn of the important role of infrared spectroscopy in the study of structure of organic compounds. To develop skill in the recognition of characteristic absorption bands. To identify a compound by an investigation of its infrared .Infrared Spectroscopy: Identifying Functional Groups you collect a spectrum, the real work begins. IR spectra of organic compounds have two general areas: .
Infrared Spectroscopy. Most of us are quite familiar with infrared radiation. We have seen infrared lamps keep food and oftenociate infrared radiation with heat..Infrared Spectroscopy. 1. Introduction As noted in a previous chapter, the light our eyes see is but a small part of a broad spectrum of electromagnetic radiation..FTIRysis uses infrared radiation to characterize chemical bonds and to identify materials. It is especially useful in identifying polymers and other organic materials, but it also has use in identifying some inorganic materials. It is used to differentiate such materials and to identify degradation processes..To learn of the important role of infrared spectroscopy in the study of structure of organic compounds.

If the frequency of the IR light matches the frequency of the vi.tion stretching or bending , the bond will absorb the energy and vi.te to a greater extent. An important concept about IR spectroscopy is that different types of bonds, hence different functional groups, have different IR absorption frequencies..
