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