Introductory note on the infrared spectrum of 1,1-dibromoethane

Students and teachers please note my explanation of the infrared spectrum of 1,1-dibromoethane is designed for advanced, but pre-university, chemistry courses.

Based in the infrared spectrum diagram for 1,1-dibromoethane, only some of the most prominent peaks for particular bond vibrations are discussed, particularly if 1,1-dibromoethane has a functional group with a particular characteristic wavenumber peak.

The infrared spectrum of 1,1-dibromoethane is unique and the whole, or selected wavenumbers, can be used to fingerprint its identity, sometimes analysing a mixture containing 1,1-dibromoethane or following its change of concentration in a reaction.

Spectra obtained from a liquid film of 1,1-dibromoethane. The right-hand part of the of the infrared spectrum of 1,1-dibromoethane, wavenumbers ~1500 to 400 cm-1 is considered the fingerprint region for the identification of 1,1-dibromoethane and most organic compounds. It is due to a unique set of complex overlapping vibrations of the atoms of the molecule of 1,1-dibromoethane.

Interpretation of the infrared spectrum of 1,1-dibromoethane

The most prominent infrared absorption lines of 1,1-dibromoethane

Several moderately strong absorption bands at wavenumbers 2975 to 2845 cm-1 for C-H stretching vibrations - collectively give the impression of strong absorption in the infrared spectrum of 1,1-dibromoethane.

Several strong absorption bands from C-H deformation vibrations at wavenumbers 1470 to 1370 cm-1.

Several strong absorption bands from 780 to 580 cm-1 due to C-Br stretching vibrations of 1,1-dibromoethane.

The absence of other specific functional group bands will show that a particular functional group is absent from the 1,1-dibromoethane molecular structure.
