In alkyl or aryl carbonates, the presence of conformational isomers (s-cis and s-trans) has been confirmed by infrared and nuclear magnetic resonance spectroscopic techniques. The dipole-moment measurements also support the conclusions obtained from the spectroscopic data.
在烷基或芳基
碳酸盐中,红外光谱和核磁共振光谱技术已证实存在构象异构体(s-顺式和s-反式)。偶极矩测量也为光谱数据所得结论提供了支持。
