trans-2,3-dimethyloxirane-2-d 1 , and trans-2,3-dimethyloxirane-2,3-d 2 are synthesized. Vibrational circular dichroism (VCD) sepctra for these compounds are obtained in the 1600-700-cm -1 region. Ab initio theoretical calculations using the localized molecular orbital method (LMO-VCD) and the vibronic coupling theoretical method (VCT) are also obtained for these molecules
合成了反式-2,3-二甲基环氧乙烷-d 0 、反式-2,3-二甲基环氧乙烷-2-d 1 和反式-2,3-二甲基环氧乙烷-2,3-d 2 的两种对映异构体。这些化合物的振动圆二色性 (VCD) 光谱在 1600-700-cm -1 区域获得。对于这些分子,还获得了使用定域分子轨道方法 (LMO-VCD) 和振动耦合理论方法 (VCT) 的从头算理论计算
