摘要: 建议了一种E.COSY型的13C-1H相关实验.在相应的13C-1H相关谱中,31P核对13C,1H核的被动偶合给出E.COSY型的谱峰裂分,可用于准确测定含磷化合物中的31P-1H和31P-13C偶合常数及其相对符号.测定了果糖-1,6-二磷酸根离子的31P-1H和31P-13C偶合常数。

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.
