A vibrational analysis of crystalline trans-1,4-polybutadiene

Abstract
The normal vibrations of crystalline trans-1,4-polybutadiene have been calculated by combining interchain atom-atom potentials with the previously proposed intrachain force field. These calculations have been used to analyze the infrared and Raman spectra of an essentially all-trans urea-complex polymer. The band splittings and low-frequency lattice modes observed in these spectra are satisfactorily accounted for by the calculations.
