The influence of methyl group rotation on the NMR spectrum of 3,5-dichlorotoluene, partially oriented in a nematic phase 来自 ResearchGate 喜欢 0 阅读量: 29 作者:P Diehl,HP Kellerhals,W Niederberger 摘要: The proton magnetic resonance spectrum of 3, 5-dichlorotoluene has been studied in the ...
Determining a structure using 13C NMR depends on a one-to-one correspondence between the number of sets of equivalent carbon atoms and the number of signals in the spectrum. Sign in to download full-size image Figure 15.22. 13C NMR Spectrum of 1-cis-3-trans-5-trimethylcyclohexane Problem ...
N-Acetate-methyl signals were examined in the NMR spectra of a series of mucopolysaccharides and some glycopeptides in reference with those of the component monosaccharides involving axial or equatorial acetamide group. The signals showed no significant change on the chemical shifts and shaps in 8 ...
Isotopically labeled methyl groups provide NMR probes in large, otherwise deuterated proteins. However, the resonance assignment constitutes a bottleneck for broader applicability of methyl-based NMR. Here, we present the automated MethylFLYA method for

The proton NMR spectra at 220 MHz of two series of substituted cyanopropionates, have been investigated. In addition the 13C spectra at 15 MHz of the series I were also studied. In I, where the R groups are diastereotopic, differences are observed in the proton chemical shifts of the CH3...
The structure determination of the alkaloid was based on NMR spectral data and hydrolysis of both the ester functions at C(14) and C(18) of elanine to afford the known alkaloid delectinine [14]. Pacinine, obtained by oxidation of the C(6) hydroxyl group of delpheline (57; R = OH)...
