Abstract

NMR spectroscopy is rarely utilized when analytes include paramagnetic ions. We show that multinuclear solid-state NMR is actually potentially useful for investigating nanostructures of a layered double hydroxide (LDH) containing paramagnetic Ni²⁺ cations. In particular, ¹³C NMR spectra of interlayer carbonate anions are well resolved by using conventional MAS/DD.
