NMR spectroscopy is a technology that is widely used in metabolomic studies. The information that these studies most commonly use from NMR spectra is the metabolite concentration. However, as well as concentration, pH and ionic strength information are also made available by the chemical shift of ...
The complete assignment of the H-1 and C-13 NMR spectra of eight thienyl-substituted chromenes was achieved by the concerted application of homonuclear (gs-COSY), H-1-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation experiments. (C) 1998 John...
High resolution FAB-MS data indicated the molecular formula C30H44O5, which is consistent with the 13C NMR data. The 13C NMR spectrum exhibited thirty signals which were assigned as shown in Table 1 by analyses of DEPT and 2D PFG-HMQC2) ... T Sato,T Hanada,M Arioka,... - 《Journa...
