Research Abstract

In this research, terahertz absorption spectra of poly-hydroxybutyrate were measured during isothermal crystallization. Two-dimensional correlation spectroscopy (2DCOS) was applied for the obtained spectra. In 2D spectra, detail of the crystallization mechanism was observed, i.e. the peaks due to hydrogen bonds developed earlier than those due to the skeletal structure of polymer crystal. By using 2DCOS, terahertz spectral become simplified and enables to reveal information about polymer structures.
