Functional Group Characteristics and Roles
WebMost organic functional groups absorb in the so-called “diagnostic region” of the spectrum at wavenumbers from 1500-4000 cm -1 and can be easily recognized. For example, carbonyl functional groups (C=O) typically show up around 1750 cm -1 and hydroxyl groups (O-H) stretches show up around 3500 cm -1 (see example spectrum below). WebNov 9, 2024 · Infrared (IR) spectroscopy is a very useful method for detecting the characteristic bonds of many functional groups through their absorption of infrared light. If you shine infrared light on a molecule, it is possible that the molecule absorbs energy from light. Absorbed energy can cause a bond to stretch or bend.We call that a stretching or … regina v anthony minehan
