Abstract
A series of experiments have been carried out to determine the origin of a broad absorption band which is found in the far infrared spectrum of almost every organic liquid. In this study, attention is focused on the homologous series of nitriles from acetonitrile to capronitrile, as well as on dimethylsulfoxide. Spectra of pure liquids, some deuterated analogs, and dilute solutions in non-polar solvents have been examined. In addition, the effect of varying temperature has been investigated for certain cases. The results will be discussed in terms of their implications with regard to the several theories for the origin of these absorptions now extant, namely, pseudolattice vibration, dielectric dispersion, hindered rotation, and molecular association.
