摘　　要：为了了解琥珀酸氢十八酯晶体 (OHS)的结构 ,本文测定了OHS晶体几何配置为 y(zx)y和 y(zz)y和几何配置为 y(xz)y和 y(xx) y的拉曼光谱 ,实验表明 :涉及到OHS烷烃链的几个振动模式都出现偏振动 ,由此可推测其晶体结构可能是以双聚体沿 [10 0 ]和 [0 0 1]方向排列成层 ,沿 [0 10 ]方向堆垛 ,OHS其他基团的拉曼光谱振动吸收峰也都相应出现。Raman spectra of crystal-octadecyl hydrogen succinate (OHS),whose geometric disposition of the experiment has (zx)y,(zz)y,and (xz)y,(xx)y respectively,have been recorded and analyzed with the purpose of understanding the structure of OHS crystal.It shows that some of the Raman-active modes of alkyl chain appear polarization.The analysis for crystal structure indicates that the molecular of OHS arrange in layers along [100] and [001] by the mode of dimers,and the molecular layers of chain pile up along [010].The other groups of OHS corresponding Raman vibration peaks have been analysized as well.
