Many compounds can be better studied using nuclei other than 1 H and 13 C:
Use of multinuclear NMR spectroscopy enables such parameters as oxidation state, complexation geometry and fluxionality of organometallic complexes and inorganic salts to be probed.
19 F is a very sensitive NMR active nucleus that provides a wealth of structural detail. The chemical shift information and coupling data (between fluorine nuclei and other atoms) found in 19 F NMR spectra allows the assignment of both the nature and location of fluorine atoms within molecules.
