Abstract

The structural analytical method for the determination of molecular bond directions and the orientational distribution relative to the oriented axis of silk fibroin fiber was studied on the basis of the solid state N nuclear magnetic resonance chemical shift anisotropy tensor. Using the unitary matrix, the matrix transformation from the principal axis system(PAS) through the fiber axis system(FAS) to the molecular syulmetry axis system(afSA), the angle, between the fiber axis and the molecular bond direction, NH and NC' bonds in Bombyx mori silk fibroin fiber are determined as well as the orientational distribution around the silk fibroin fiber axis, p was also obtained. The structural parameters determined for silk fibroin fiber are compared with these obtained by X-ray diffraction.
