infrared spectrum of 1-iodopropane C3H7I CH3CH2CH2I wavenumbers cm-1 functional group detection fingerprint pattern identification of propyl iodide doc brown's advanced organic chemistry revision notes 

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

Interpretation of the infrared spectrum of 1-iodopropane

The most prominent infrared absorption lines of 1-iodopropane

C-H stretching vibration absorptions. peaking at wavenumbers ~2845 to 2975 cm-1.

C-H bending/deformation vibrations absorption bands peaking at wavenumbers ~1370 to 1470 cm-1.

C-C-C skeletal vibrations from the CH3-C-CH3 grouping occur at wavenumbers ~1140 to 1175 cm-1. and 840 to 790 cm-1.

Characteristic groups of C-I stretching vibration absorptions at wavenumbers ~600 to 500 cm-1.

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