The relaxation rates of 27Al, H, D, 17O, and the relaxation rate of H due to dipolar coupling to 17O were obtained in a series of aqueous AlCl3 solutions. From these data conclusions are reached about bulk water dynamics, the O–H bond distance, and the order within the Al3+ hydration shell. The bulk water dynamics is interpreted by a hydrodynamical model. For comparison viscosity data are presented. It is found that the change in the O–H distance of water molecules adjacent to Al3+ is significant and in agreement with reported theoretical results. The destruction of order within the Al3+ hexaquo complex with increasing concentration is indicated.
