The infrared spectrum of benzene is unique and the whole, or selected wavenumbers, can be used to fingerprint its identity, sometimes analysing a mixture containing benzene or following its change of concentration in a reaction.
determine whether an unknown compound contains an aromatic ring by inspection of its infrared spectrum, given a table of characteristic infrared absorptions. state the approximate chemical shift of aryl protons in a proton NMR spectrum.

This article will provide a table containing the IR spectrum frequency values and the molecules they represent.
1 mar 2016 · Figure 3: The IR spectrum of benzene, measured as a capillary thin film between two KBr windows. As you read the spectrum of benzene from left to right, note there are three peaks between 3200 and 2800 cm-1, making these C-H stretches.
1 maj 2016 · We will examine numerous example spectra and learn how the position of C-H wagging peaks, and the presence or absence of a ring-bending peak, allow one to distinguish between mono-, ortho-, meta-, and para-substituted rings most of the time.
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
