Group Wavenumbers and an Introduction to the Spectroscopy of Benzene Rings
March 01, 2016
IR Spectral Interpretation Workshop
Continuing our theme of investigating the infrared spectra of hydrocarbons, we look at the nature of aromatic bonding and why aromatic rings have unique structures, bonding, and infrared spectra. Then we examine, in detail, the spectra of mono- and di-substituted benzene rings, and learn that infrared spectroscopy easily distinguishes between ortho-, meta-, and para- structural isomers.
