摘　　要：测定了OAO粉末衍射、红外光谱和几何配置为y(zx)y、y(zz)y和 y(xz) y、 y(xx) y的拉曼光谱 .实验结果表明 ,OAO晶体最强衍射 2d =9.0 716nm ,拉曼光谱中烷烃链的几个振动模式出现偏振 ,由此可推测其晶体结构是沿 [10 0 ]和 [0 0 1]方向排列成层 ,分子层间沿 [0 10X-ray powder diffraction, IR spectra and Raman spectra of crystal-adipates dioctadecyl (OAO), whose geometric disposition of the experiment y(zx)y, y(zz)y, and (xz), (xx) respectively, have been recorded and analyzed. It shows that the diffraction intensity of plane spacing 2d=9.071?6?nm is the strongest of all diffraction face in OAO crystal, and some of the Raman-active modes of alkyl chain appear polarization. It is possible that the molecular of OAO arrange in layers along and , and the molecular layers of chain pile up along .
