WebNov 30, 2015 · The spectrometer detects this absorption and records it as a peak in a plot of transmission versus frequency. Within a narrow range, each type of bond vibrates at a characteristic wavenumber. This makes infrared spectroscopy useful to identify functional groups in a molecule. Here’s a short table of common absorption frequencies. 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). philips razor sent backWebTable 1: Principal IR Absorptions for Certain Functional Groups Functional Group Names & Example compounds Absorption Ranges(cm-1) [Look for a single absorption in these regions, unless stated otherwise.] Type of Vibration causing IR absorption 3000-2800 (Note: The absorptions can be seen as several distinct peaks in this region.) trwqpopular now on binge
