A normal vibration analysis has been carried out for crystalline syndiotactic poly(vinyl chloride) and its deuterated derivatives. This was based on a general valence force field derived from an analysis of the spectra of small secondary chloride molecules. The calculations permit a very satisfactory assignment to be made of the observed bands in the IR and Raman spectra, including the low frequency region.
