摘要：

The Fourier transform infrared and Raman spectra of the semi-flexible main-chain thermotropic liquid crystal polyester, poly(heptamethylene terephthaloyl-bis-4-oxybenzoate) are presented, and tentative band assignments given. The polymer is investigated as a function of its thermal history, and Fourier transform Raman spectra are recorded with temperature using a high-temperature cell. The results are discussed along with calorimetric and X-ray scattering data. Spectral evidence is presented which is related to both the sample crystallinity, and the crystal-to-liquid crystal phase transition.
