Infrared-Absorption Spectra of Chloro-, Bromo-, and Iodoalkanes in the 400-to-100-cm−1 Region

Abstract
The infrared‐absorption spectra of 18 haloalkanes have been studied and the carbon—halogen bending vibration assigned for each molecule. The effect of rotational isomerism on this vibration was determined. The low‐frequency torsional modes have also been assigned. Solid‐state studies contributed to the support of the assignments and made it possible to determine rotational effects.
