WebConsequently tables of IR absorptions are arranged by functional group -- it some versions these may be further subdivided to give more precise information. In IR absorption tables, signal intensities (height) are usually … WebIR Spectroscopy Tutorial: Aromatics The = C–H stretch in aromatics is observed at 3100-3000 cm -1. Note that this is at slightly higher frequency than is the – C–H stretch in alkanes. This is a very useful tool for interpreting IR spectra: Only alkenes and aromatics show a C–H stretch slightly higher than 3000 cm -1.

To summarize then, the IR spectra of alkenes are characterized by one or more C-H stretching peaks between 3100 and 3000, a possible C=C stretch from 1680 to 1630, and one or more C-H wagging peaks from 1000 to 600.
