| Abstract: | An E.COSY-type 31P-1HH correlation experiment is described. In the resulting spectrum, the passive couplings to the 31P-1H spin pair from 31P nucleus give E.COSY-type splittings, which can be used for accurate measurements of heteronuclear 31P-1H and 31P-13C coupling constants. The heteronuclear 31P-1H and 31P-13C coupling constants of Furctose-1,6-diphosphate anion are measured. |
