Solid-State 23Na Nuclear Magnetic Resonance of Sodium
... In general, solid-state 23Na NMR spectra of sodiumionophore complexes were obtained using MAS and high-power proton decoupling. Under such circumstances, the observed central-transition 23Na NMR spectra exhibit typical features arising from second-order quadrupole interaction. In most cases only a s ...
