✦ Synopsis

The "A1 chemical shifts, line widths and intensities have been measured for a series of sodium aluminate solutions with a range of sodium and aluminium concentrations. The aluminium is present entirely as the anion [Al(OH),Iin all but the most concentrated solutions, where intensity is lost owing to the formation of species with very broad lines. The viscosities of the solutions were also measured and it was shown that these accounted to a great extent for the observed changes in line width, so that the unusually wide lines seen in the most concentrated solutions cannot be said to arise from dimeric species.
