Charateristic IR Absorption of Benzene Derivatives Arenes have absorption bands in the 650-900 cm −1 region due to bending of the C–H bond out of the plane of the ring. The Mid-FT-IR Spectrum of Benzene is shown below: The IR spectrum for benzene, C6H6, has only four prominent bands because it is a very symmetric molecule. evaluated Anhand der Lage dieser Banden ist eine Identifizierung der Substitutionstypen der Aromaten möglich.

Practice with identifying the compound that corresponds to an IR spectrum. (2-Methylpropyl)benzene. The technical uses of the compound are limited, although it is recommended as a solvent in a number of photochemical reactions. Infrared spectral interpretation may be applied to both organic and inorganic compounds, and there are many specialized texts dealing with these compounds, in combination and as individual specialized texts. The IR spectra of gaseous nitrobenzene (NB) and its 15N isotopomer have been obtained in the frequency range of 3500–250 cm−1, and the far-IR spectra of their solutions and the NB neat liquid sample have been recorded in the range of 600–30 cm−1. , compared with UV-Visible spectra, is characteristic are limited, although is...
