In continuation of earlier work by the authors in which torsional bands were observed in the far-infrared spectra of 2-propanethiol and cyclohexanethiol, torsional bands also have been observed for ethanethiol, 2-methyl-2-propanethiol, n-propylamine, isopropropylamine, and t-butylamine. In the alkanethiols, force-constant calculations show that interactions between SH and CH/sub 3/ torsions are relatively unimportant; however, in contrast, interactions between NH/sub 2/ and CH/sub 3/ torsions are important in the alkylamines. Methanethiol vapor has a complex set of infrared bands between 60 and 500 cm/sup -1/ that arises from coupling between internal and overall rotation.
