摘要: 定域谱和二维谱技术都是NMR的重要研究手段.定域二维谱,就是将二者结合,同时具有空间信息和二维谱的诸多优点.本文利用STEAM脉冲序列加以改造,完成了三维空间定域的二维1H-1H NOESY实验.

关键词: 空间定域, 二维谱, STEAM, NOESY

Abstract: Spatially localized one-and two-dimensional NMR spectroscopy has been demonstrated on a MRI system with a phantom sample of methyl methacry lete-naphtyl ethylene copolymer.The conventional STEAM pulse sequence has been implemented for 2D NOESY experiment by inco rporating increment time t1. The results show high efficiency of suppression of the unwanted signal of H2O by volume selection. The methods have potential application in vivo MRS study for obtaining valuable information.
