Abstract

Triple-quantum 23Na MAS NMR spectroscopy has been applied to characterize the three polymorphs of sodium acetate. The crystallographically distinct sodium sites in each of these polymorphs are uniquely identified from the triple-quantum 23Na MAS NMR spectra. These data provide access to the 23Na quadrupole interaction parameters (quadrupole coupling constant and asymmetry parameter) for each sodium site, which provide a quantitative measure of the local structural properties of the sodium cations in each polymorphic form.
