Abstract: | The rotational isomerism of 1-bromopropane, 1-chloro-2-methylpropane and 1-bromo-2-methylpropane has been studied in the liquid phase by infrared spectroscopy. For the corresponding conformers the enthalpy differences were obtained from the temperature dependences of the intensities of the CX-stretching and some CCC-deformation vibrations. It was found that only the CX-stretching vibrations are suitable for enthalpy determinations. In the liquid phase those conformers with a gauche position of the methyl group and halogen atom are slightly preferred. |
