Spectroscopy Tutorial: Alkyl Halides


IR Spectroscopy

Alkyl halides do not show any really distinctive bands. The C–X stretches show in the region less than 725 and thus are usually hard to distinguish from both other bands in the area and drop-off from the salt plate.

NMR Spectroscopy

The proton on the same carbon as the halide is shifted to 2-4.5 ppm, depending on the halide.
