Abstract: IR spectra of high cis-rolybutadiene were measured at both room temperature and -150℃. Spectral changes related to the crystallization were observed. The profile change of the 738 cm-1 band was attributed to the change in the molecular chain conformation, especially to the change in the internal totational angle of the single bonds adjacent to the C=C double bonds.
