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~...
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...
