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谱 1. Each fraction was analyzed qualitatively by1H-NMR spectra,then the aromatic fraction was characterized using gas chromatograph/mass spectrometer(GC-MS). 通过1H-NMR谱图对各族组分的切割点的准确性进行了定性分析,并用色-质联用对循环油的芳烃组分进行了分析,初步确定了基本组成,为煤液化油的...

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...
ADF LOGO > Spectra: 这是没有自旋-自旋耦合的结果。每个峰都对应着某个原子,点击这些原子,对应的峰也被选中了。对这个分子而言,中间的两个H原子是等价的,因此可以进行平均:选中左边窗口的这两个H原子,按Ctrl G(或者点击菜单Regions → New Region From Selected Atoms)这样,谱图就对这两个H原子进行了平均。

Deciphering1H-NMR Spectra One of the most important concepts taught in organic chemistry is the method for determining the chemical structure of newly synthesized or unknown compounds. In this article, we will summarize the concept of proton NMR, the most common NMR information acquired by organic ...
