Abstract :
Terahertz absorption spectra of Poly(3-hydroxybutyrate)s were measured. The orientation of the transition dipole moment was investigated by the polarization spectra. The temperature dependence of the spectra reflects the change in the hydrogen bonding distance of the crystalline structure.
