Abstract: Infrared absorption spectroscopy was used to study molecular orientation of ordered and disordered regions of polyethyleneterephthalate fibers. Experimental data were employed to calculate the factors of orientation of ordered and disordered regions. The orientation factors calculated in this way were compared with those obtained from X-ray structure analysis and sound velocity measurements. The orientation of ordered regions was evaluated from dichroism of the absorption band at 437 cm^-1 and the orientation of disordered regions from dichroism of the absorption band at 502 cm^-1.
