| Abstract: | The low resolution microwave spectra of a series of 1-haloalkanes were studied. With the exception of 1-bromobutane only the all s-trans conformer and those gauche conformers in which a single dihedral angle is gauche were foud. By analyzing data from a homologous series, a gauche dihedral angle of 286 ± 4° was determined for the gauche conformers of the bromo and iodo species. An analysis of relative intensities of the 1-bromobutane and 1-iodobutane bands yielded standard Gibbs free energy differences. |
