本文报道了十个不对称取代1,3,2-二氮磷杂环戊烷的~(13)C 核磁共振谱,利用~(13)C 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。
In this paper, ~ (13) C nuclear magnetic resonance spectra of ten asymmetric substituted 1,3,2-diazaphospholanes were reported. The ~ (13) C spin-lattice relaxation time was used to determine the Even if the technique is difficult to determine the attribution of the signal, the relationship between the coupling constant and the conformation is discussed.
