2D NMRThe objective of this study was to identify molecular alterations in the human blood serum related to bipolar disorder, using nuclear magnetic resonance (NMR) spectroscopy and chemometrics. Metabolomic profiling, employing1H-NMR,1H-NMR T2-edited, and 2D-NMR spectroscopy and chemometrics of ...
Here, we propose a new method that exploits the differential T* relaxation times of individual resonances and resolves the 2D NMR peaks into pseudo-3D spectra, where time is the 3dimension. T* weIghted DEconvolution or TIDE analyzes individual free induction decays (FIDs) and dissects them into...
Escherichia coli diacylglycerol kinase (DGK) is an integral membrane protein, which catalyses the ATP-dependent phosphorylation of diacylglycerol (DAG) to phosphatic acid (PA). It is a unique trimeric enzyme, which does not share sequence homology with t
这一结果说明,非晶结构域中的1,4-BDC与多晶结构域的CoOOH相结合,排除了混合形式的Fe-Ni-CoOOH-TPA存在,并与SSNMR结果相符。 Figure 4. (a) In situ Raman spectra of Fe−Ni−Co-MOF as a function of the number of cycl...
我最近测了一组27Al 2D MAS NMR，用Mestrenova对数据进行处理，但是不知道怎么计算四级耦合常数。不对称...

Six samples of a spent catalyst from a HDT reactor have been analyzed by 29Si MAS. 29Si CP/MAS, and 13C CP/MAS NMR spectroscopy. From these studies it is concluded that the silicone oil in the naphtha feed is transformed (oxidized) to modified silica gels, i.e., silica with a ...
XPS和^29Si MAS NMR在不同分子筛的化学组成及电子结构中?… 采用光电子能谱和Si核磁共振及化学分析方法研究了五种不同分子筛纳型和钾型的化学组成。结果发现,分子筛的Al/(Si+Al)比和骨架Al/(Si+Al)比与其体相Al(Si+Al)比具有一... 周灵萍,李伟 - 《南开大学学报:自然科学版》 被引量: 1发表: 1999...
