WebThis is a very useful tool for interpreting IR spectra: Only alkenes and aromatics show a C-H stretch slightly higher than 3000 cm -1. Compounds that do not have a C=C bond show C-H stretches only below 3000 cm -1. The strongest bands in the spectra of alkenes are those attributed to the carbon-hydrogen bending vibrations of the = C–H group.
