Accurate Heteronuclear J-Coupling Measurements in Dilute Spin Systems using the multiple-quantum filtered J-resolved experiment

Résumé

A new solid-state MAS NMR experiment is proposed to accurately measure heteronuclear 19F–207Pb J-coupling constants, 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 multiplequantum filtering considerably improves the resolution of J-multiplet patterns for dilute spin systems.
