摘　　要：为了进一步了解马来酸氢十八酯晶体 (OHM )的结构 ,本文测定了OHM晶体几何配置为( y(zx) y)和 y(zz) y和 ( y(xz) y和 y(xx) y) 的拉曼光谱 ,实验表明OHM烷烃链的几个振动模式出现偏振 ,晶体结构分析表明在OHM晶体中分子是以双聚体沿 [10 0 ]和 [0 0 1]方向排列成层 ,沿 [0 10 ]方向堆垛 ;Raman spectra of crystal octadecyl hydrogen maleate(OHM),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 OHM 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 OHM 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 OHM corresponding Raman vibration peaks have been analysed as well.
