核磁共振一维同类核相关编辑

本文用自旋密度算符理论分析了“硬”脉冲回波序列所得到的一维核磁共振同类核相关编辑问题。提出的实验方法与理论分析预期一致,并证明这种同核相关编辑的结果与二维核磁共振COSY谱所揭示的相关关系一致,但是一维相关编辑具有省时,节约内存和保留一维谱的灵敏度和分辨率以及保留谱的精细结构等优点。 关键词：

1 DIMENSIONAL NMR HOMONUCLEAR CORRELATION EDITING

The "hard" pulse sequences with spin echo for one dimensional homonuclear correlation editing (1 D HCE) are discussed with density operator theory. The experimental results coincides with the theoretical expectation. It is shown that the correlation obtained from I D HCE spectra is similar to that from COSY. The advantages of this technique are: 1) saving time, 2) saving computor memory, 3) keeping the sensitivity, resolution and the fine structure of 1 D NMR spectra.
