用固体~1H MAS NMR研究水在不同吸附质中的状态 应用固体^1H MSA NMR实验技术,根据核磁共振峰线宽的不同,表征了水在不同吸附质中的微观状态.在含水的壳聚糖和明胶中,以氢键形式存在的水的共振峰线宽为2000Hz 左右.在... 赵晓东,孙平川 - 《离子交换与吸附》 被引量: 0发表: 2001年 吡咯表征分子筛碱性的~...
The combination of magic angle spinning (MAS) with the high-resolution 1H NOESY NMR experiment is an established method for measuring through-space 1H… 1H dipolar couplings in biological membranes. The segmental motion of the lipid acyl chains along with the overall rotational diffusion of the lip...
NMR spectrum,without needing extra acquisition time.In this paper,STOCSY was used to analyze HR-MAS 1H spectra of rat kidney tissue.Pseudo 2D spectra were generated from a set of 1D HR-MAS NMR spectra and used to observe intramolecular correlations among the resonances.The STOCSY results are...
