This had been established in 1H NMR studies of animal brains in vivo which started in our laboratory in 1983 (these studies are reviewed in Avison, Hetherington, and Shulman, 1986 J.W. Prichard and R.G. Shulman Ann. Rev. of Neuroscience 9, 61–85 (1986) . Since our lab received a ...

1H NMR spectra were recorded on an Avance-400 spectrometer with d6-DMSO (dimethyl sulfoxide) as the solvent at room temperature and TMS (tetramethylsilane) as the internal standard.UV–Vis (UV–visible) spectra were recorded on a Perkin–Elmer Lambda-25 spectrophotometer,and emission spectra ...
a1H-NMR spectra were measured on a Bruker Avance 300 spectrometer operating at 300 MHz (DMSO-d6 solutions using TMS as internal reference) 1H核磁共振的光谱在经营在300兆赫(DMSO-d6的Bruker Avance 300分光仪被测量了解答使用TMS作为内部参考) [translate] ...
The 1H NMR spectra of variously annulated pyranocoumarins are reported. The complete assignment of chemical shifts was achieved by using coupling constants and the shift effects induced by the introduction of methyl groups at various positions on the pyranocoumarin nucleus, and by comparison with the...

that allow one to identify individual coupling constants within even the most complex first-order multiplets likely to be encounteredin lH NMR spectra. It also provides a set of graphical representations (Cand Tables 1-11)for assisting in empirical, visual pattern recognition. A first-order multiple...

Fig.2 Comparison of raw and aligned1H NMR spectra of wine samples: Raw (A) and aligned (C)1H NMR spectra in the region (1.95-2.05) ppm; Raw (B) and aligned (D)1H NMR spectra in the region 3.73-3.76 ppm 适当的峰化学位移偏移校正对齐对随后的多元变量分析至关重要。化学位移偏移会引起化...
It is shown how the secular determinant for the general four-spin case can be greatly simplified in the case of NMR spectra of the AA′XX′ and AA′BB′ type on the basis of molecular symmetry and with the aid of the so-called X approximation. The methods for the direct analysis of ...
