Orientation parameters related to the C.tplbond.N stretching vibration and the CH2 deformation vibration absorption bands in the three film coordinate directions were obtained from 3-dimensional measurements on uniaxially drawn polyacrylonitrile [25014-41-9] films with linearly polarized ir radiation. The ir data were combined with x-ray diffraction measurements to characterize the type and degree of mol. orientation.
