By using a modified Shirakawa catalyst Lugli et al. [1] have prepared f'dms which can be stretched up to 7 times their original length. This highly oriented material has been examined using various techniques. X-ray data [2] have shown an almost perfect alignment of the polymer fibers along the stretching direction. Polarized infrared spectra [3; 4] have provided an unambiguous assignment for the odd parity phonons of the undoped polymer both in its cis and trans configurations. Moreover the polarization properties of the doping induced infrared bands have been unambiguously determined for the first time [4; t hus providing * This work has been in part presented at the IXth International Conference on Raman Spectroscopy; Tokyo; Japan; August; 27-September; 1; 1984.
