Notes:
Conventional liquid-state 27Al NMR spectra of concentrated solutions of the AlCl3-water-N,N-dimethyl-N-Dimethylformamide formamide system contain comparatively broad non-structured lines. Application of MAS leads to a reduction in the line width and a structuring of the spectra. This allowed the experimental determination of the chemical shifts of [Al(H2O)6-x(DMF)x]3+ (x = 0-6) mixed-ligand complexes. The investigations demonstrate an example of the applicability to liquids of the NMR MAS technique, which was originally developed for solids. They underline the existence, in a reduced form, of ‘solid-type’ interactions within the investigated solutions.
