摘要：

Detailed diffractometer and Laue x-ray studies of stretched poly(3-hexylthiophene) films enabled us to identify several 00l reflections associated with the polymer chain direction. The chain repetition distance could then be determined for the first time, giving c = 2.7.4 angstrom = 14.8 angstrom. 7.4 angstrom is shorter than expected for a model involving "alternating up-down" monomers along the chain (7.8 angstrom), whereas the observed c value is in agreement with a new "up-up-down-down" model (14.9 angstrom). Intensity calculations assuming side chain disorder corroborate well with the new model.
