摘要： 本文介绍一种¹H-¹³C远程极化转移的脉冲序列.在JEOL FX-90QNMR波谱仪上实现了这种技术.对一些典型化合物的测定表明,选择性非灵敏核的远程极化转移增强法(SEL1NEPT)在测定季碳原子和进行谱带归属中,是一个有力的工具.

关键词: 选择性非灵敏核极化转移增强法

Abstract: A pulse sequence of polarization transfer via long-range ¹H-¹³C couplings is introduced. This technique has been carried out on a JEOL FX-90Q NMR spectrometer. It is demonstrated that the selective insensitive nuclei enhancement by polarization transfer via long-range ¹H-¹³C couplings (SELINEPT) is a powerfull tool for measuring quaternary carbon atoms and assignment of the peaks in ¹³C spectra through determining some model compounds.

Key words: SELINEPT
