The 1H and 13C NMR spectra of the dinuclear complexes of molybdenum(VI) withethylenediaminetetraacetic acid ([Mo(VI)]2-EDTA) and 3,12-bis(carboxymethyl)-6.9-dioxa-3,12-diazatetra-decanedioic acid(tMo(VI)]2-EGTA) at va...The 1H and 13C NMR spectra of the dinuclear complexes of molybdenum(VI) withethylenediaminetetraacetic acid ([Mo(VI)]2-EDTA) and 3,12-bis(carboxymethyl)-6.9-dioxa-3,12-diazatetra-decanedioic acid(tMo(VI)]2-EGTA) at various temperatures were measured. The solutionstructure of the two dinuclear complexes was determined and the possible exchange process of theisomers is suggested展开更多

The 3-line spectrum comes from the conformation of the radical R1 which usually corresponds to a 6-line typical spectrum but appear as an apparent 3-line spectrum in solid state.The 12-line specturm comes from two speciesof radicals with the same conformation R2 but different G factor .R2 corresponds to a 8-line typical spectrum which appear as an apparen in the hing-viscosity solution. therefore, two apparent 6-line spectra of R2 with different g values form the 12-line spectrum.展开更多
