[The Raman spectra study on crystal-octadecyl hydrogen succinate crystal].
Raman spectra of crystal-octadecyl hydrogen succinate (OHS), whose geometric disposition of the experiment has y(zx)y, y(zz)y, and y(xz)y,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 analyzed as well.
