摘要：

A new solid-state MAS NMR experiment is proposed to accurately measure heteronuclear F-19 - Pb-207 J-coupling constants, even though these couplings are not visible on high speed F-19 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.
