摘要/Abstract

摘要： 本文建议使用多量子滤波方法来提高一维谱的分辨率,从而可从堆集在一起的谱中获得耦合的信息,并从理论上证明了此方法的原理主要是由于反相磁化信号的测量而不是正常磁化信号,它与弛豫的作用无关。

关键词: 反相磁化, 双量子滤波, 改善分辨率

Abstract: It is proposed that the resolution of 1D-NMR spectra can be improved by means of multiple quantum filter thereby the coupling information from the overlapped spectra can be obtained.It is proved theoretically that this method is in principle to observe the anti-phase magnetization instead of the normal magnetization and is generally independent on relaxation.

Key words: anti-magnetization, DQF, resolutionimprovement
