Ir spectra groups
WebInfrared Spectra of Some Common Functional Groups Objectives After completing this section, you should be able to use an infrared spectrum to determine the presence of functional groups, such as alcohols, amines and carbonyl groups, in an unknown compound, given a list of infrared absorption frequencies. Study Notes WebDec 27, 2024 · IR spectra of organic compounds have two general areas: 4000-1500 cm -1. 1500-400 cm -1. The Functional Group Region. Peaks in this region are characteristic of specific kinds of bonds, and therefore can be used to identify whether a specific functional group is present. The Fingerprint Region. Peaks in this region arise from complex ...

The intensity of an absorption band depends on the polarity of the bond, and a bond with higher polarity will show a more intense absorption band.
