Abstract :The Raman spectra of cis- and trans-1,4- polybutadiene were recorded in the region 100-4000 cm-1 and its infrared spectra were also measured in the wave number range 200--4000 cm-1. The spectra were completely analysed. Probable assignments to observed bands were made with the help of intensities and normal co-ordinate analysis. The calculated normal frequencies were in good agreement with the experimental ones.
