Abstract
Normal modes and their dispersion are obtained for planar zig-zag form of poly(β-hydroxybutyrate) using Urey–Bradley force field. A comparison is made with the spectra of its helical form. Apart from detailed assignment of modes, various characteristic features of dispersion curves have been explained as arising due to internal symmetry in energy momentum space. The density-of-states have been used to calculate heat capacity in the temperature range 10–450 K using Debye's formalism.
