Abstract
The N-15 CP NMR spectra of three kinds of polyamide fibers: silk fibro in, poly(p-phenylene-terephthalamide) and poly(m-phenylene-isophthalam ide), were observed. The fiber axes were set parallel and perpendicula r to the applied magnetic field. The angles of the NH and NC' bonds of the amide groups relative to the fiber axes were determined according to the equations derived from the solid state NMR theory with the N-1 5 chemical shift tensors in the preceding paper. This analytical metho d is very useful in the structural study of the non-crystalline domain s in polyamide fiber.
