✦ Synopsis
Conventional liquid-state "A1 NMR spectra of concentrated solutions of the AIC1,-water-N,Ndimethyl-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 (AI(H,O), -,(DMF)$+ (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. KEY WORDS "A1 NMR spectroscopy MAS technique Concentrated electrolyte solutions
