Production and NMR characterization of hyperpolarized (107,109)Ag complexes

Angew Chem Int Ed Engl. 2012 Jan 9;51(2):525-7. doi: 10.1002/anie.201106073. Epub 2011 Oct 13.


Both isotopes of silver, (107)Ag and (109)Ag, were simultaneously polarized by dynamic nuclear polarization (DNP), thus allowing large signal enhancements and the NMR characterization of Ag complexes in the millimolar concentration range. Since both isotopes have long relaxation times T(1), the hyperpolarized NMR signal of one isotope could still be observed even after the magnetization of the other isotope had been destroyed by radio-frequency pulses.
