本文报道了十个不对称取代1,3,2-二氮磷杂环戊烷的^1^3C核磁共振谱, 利用^1^3C自旋-晶格弛豫时间确定了用其它去偶技术难以确定的信号的归属, 讨论了偶合常数与构象的关系.

The chem. shifts and coupling constants of a series of new asym. substituted 1,3,2-diazaphospholidine compounds, were determine Furthermore, the spin-lattice relaxation time T1 of 2-(diethylamino)-1-(p-methylbenzenesulfonyl)-3-(4',6'-dimethoxyl-s-triazi n-2-yl)-1,3,2-diazaphospholidine (I) was measured. The assignment of the 13C signals, which is hard to determine with other decoupling techniques, was based on the calculated dipolar relaxation time T1DD. The relationship between the coupling constant and the configuration was described.
