高分辨固体~（13）C NMR谱已从动物源的高度结晶纤维素衣素中获得。该材料的光谱包含相对窄的谱线，并且在Cl、C4和C6处观察到峰多重性。在C1和C4处的双组分多重态表明，衣蛋白主要由1/3异晶型组成（如VanderHart和Atalla所定义的）。被膜素的光谱与从Valonia oentricosa和棉花的结晶区记录的光谱进行了比较。
High-resolutionsolid-state 13C NMR spectra have been obtainedfrom tunicin, a highly crystalline cellulose of animal origin. The spectra of this material contained relatively narrow lines, and peak multiplicities were observed at Cl, C4, and C6. Two-component multiplets at Cl and C4 indicate that tunicin consists principally of the 1/3 allomorph (as defined by VanderHart and Atalla). The spectrum of tunicin was compared with those recorded from Valonia oentricosa and the crystalline regions of cotton.
