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.
