'Accurate Heteronuclear J-Coupling Measurements in Dilute Spin Systems using the multiple-quantum filtered J-resolved experiment'
, Chem. Commun. 2720-2722 (2007) doi:
10.1039/b703321d
A new solid-state MAS NMR experiment is proposed to accurately measure heteronuclear 19F-207Pb J-coupling constants, 10 even though these couplings are not visible on high speed 19F 1D MAS spectra. In particular, we demonstrate that the J-resolved experiment combined with scalar multiple-quantum filtering considerably improves the resolution of J-multiplet patterns for dilute spin systems.
