摘要：

In this paper, we will show a unique graphical representation for the information content of 15N CP NMR spectra obtained from oriented samples placed parallel to the applied magnetic field. In particular, the 15N chemical shifts of the oriented polymers are sensitive to the angle between various molecular fixed axes and the axis of polymer alignment, especially the angle between the NH bond vector and the fiber axis, θNH. Three kinds of oriented samples whose θNH values are quite different are chosen here for experimental illustration.
