Spectral Characteristics of the Benzene Ring

The UV-visible spectrum of benzene reveals its electronic structure 

The infrared spectrum reveals substitution patterns in benzene derivatives 

The infrared spectra of benzene and its derivatives show characteristic bands in three regions. The first is at 3030 cm for the phenyl-hydrogen stretching mode. The second ranges from 1500 to 2000 cm and includes aromatic ring C-C stretching vibrations. Finally, a useful set of bands due to C-H out-of-plane bending motions is found between 650 and 1000 cm
