The subject of the study is the structure and conformation of 1″,4″-Dispiro-cyclohexane-6,6′-bis(benzothiazoline), a dispiro compound that has a cyclohexyl ring flanked by two benzothiazoline rings on either side. Using single crystal X-ray diffraction measurements, Infra-red absorption, and Raman spectroscopy techniques, it is found that the central cyclohexyl ring assumes the chair conformation and
研究的主题是1'',4''-Dispiro-cyclo己烷-6,6'-bis(benzothiazoline)的结构和构象,这是一种双螺化合物,在其两侧均带有一个环己基环,两侧是两个benzothiazoline环。使用单晶X射线衍射测量,红外吸收和拉曼光谱技术,发现中央环己基环呈椅子构型,并且两个苯并噻唑环中的硫,氮原子均处于反式构型。通过使用Gaussian 09程序套件在B3LYP / 6-311 ++ G **的理论水平上进行几何优化和频率计算,进一步证实了实验结果。
