摘要/Abstract

摘要： 用选择照射方法研究了N-甲基异靛蓝(isoindigatin)在(CD₃)₂CO、CDCl₃、DMSO-d₆溶剂中及重水交换后的¹H NMR谱。得到了化学环境极为类似的两芳环质子在不同溶剂中的NMR谱线归属和偶合常数。

Abstract: The ¹H NMR spectra of N-methyl-isoindigatin in(CD₃)₂CO,CDCl₃, DMSO-d₆ and after D₂O exchange were investigated by means of selective irradiation method. The ¹H-¹H coupling constants and the assignment of ¹H NMR spectral lines of protons with extremely similar chemical envelopments were obtained.

Key words: Isoindigatin, Selective irradiation, Selective decoupling
