Abstract
Making use of the low pressure, water‐cooled Hg arcs as the source of nearly monochromatic radiation, a simple method was developed for the investigation of the Raman spectra of polycrystalline solids. The method was applied to the study of the first four normal paraffins. The Raman spectra of the solids between 600–1500 cm−1 are compared with those in the liquid phase. All these spectra undergo a marked simplification on solidification due to the disappearance of all but one of the rotational isomers. This process is shown to be discontinuous at the melting point.Keywords
