Spectral analysis was performed by integrating peak areas after line fit of the water (i.e. peak at 4.7ppm) and fat (i.e. (CH 2) n 2 methylene peak at 1.3ppm) resonances using the Nuts-PPC software package (AcornNMR, Inc... D Laurent,B Yerby,F Sari-Sarraf,... 被引量: 5发表...
In addition,unless one purchases it in the relatively expensivedeuterated form, it adds three more signals to thespectrum (methylenes 1, 2, and 3 appear at 2.91, 1.76,and 0.63 ppm, respectively). We suggest that the re‑sidual HDO peak be used as a secondary reference; wefind that if...

也可以更改peak的峰值字体和颜色。打印即可。 补充:用Edit–Mark all- Copy可以将NMR图谱copy到word文档中,而将文件完全copy出来需要在特定的软件中读取。 12.1.1补充:可以用efp代替em/ft/abs三个命令。 操作程序 1.到108氮气泵房,检查“淄博”的气压计是否打开,已经调好(5左右)。 2.到NMR房,打开计算机程序...

40 ppm peakX-ray diffractionTPRCeO 2– γ-Al 2O 3 mixed oxides have been prepared by using both co-precipitation and impregnation methods followed by calcination at 650°C and investigated by 27Al MAS NMR, powder X-ray diffraction and temperature programmed reduction techniques to understand ...
The beta/alpha peak height ratio of ATP. A measure of free [Mg2+] using 31P NMR From 31P NMR measurements made in vitro at 38 degrees C, I = 0.25, pH 5. 75-8.5, and calculated free [Mg2+] from 0 to 5 mM, we show that, within the physio... K Clarke,Y Kashiwaya,MT King...
The tetrahedral center of the intermediate bound to the enzyme gave a unique signal appearing at 104 ppm. Separate signals were observed for free EPSP (152 ppm) and EPSP bound to the enzyme in a ternary complex with phosphate (161 ppm). These peak assignments account for our quantitation of...
