A correlation model was proposed on the basis of the preferred conformation with the observed 13C NMR chemical shift nonequivalences of these amides .

根据实验数据提出一种分子优势构象与~（13）CNMR化学位移不等性的相关模型。

The calculated results show that their interconversion paths are consistent basically , the preferred conformation is α - side-exo - [ 3333 ] - 2-one and the interconversion energy barrier is increased along with the increase of the volume augmentation of the substituent groups .

动态分析带有不同取代基的α角顺取代和α-边外取代[3333]-2-酮构象的相互转化的结果表明，它们的转换路径基本一致，转换能垒随着取代基体积的增大而升高。
