Abstract : Hydrated gallium sulfate has been studied over a wide temperature range using both steady-state and transient proton resonance techniques. Second moment and spin-lattice relaxation time data support the suggestion that oxonium H3O(+) ions exist in this material and that the structural formula should be written (H3O)Ga3(OH)6(SO4)2. The oxonium ions undergo thermally activated reorientations and translational diffusion. These motions induce dipolar proton spin-lattice relaxations which are most effective at 135 and 300K, respectively. (Author)
