Aromatic-Ring-Proton Determination by Infrared-Intensity Measurement in the 1650–2000-Wavenumber Region
The infrared absorption spectra of aromatic compounds in the 1650–2000-cm−1 region are well known to be characteristic of ring substitution patterns.(1) The observed frequencies in benzene derivatives have been assigned to overtones and combinations of =CH out-of-plane deformations.(2) The absorption in this region has been employed for the determination of total aromatics in petroleum distillates.(3)
