N2 - The concentration dependences of the 2H spin-lattice relaxation rate in aqueous solutions of certain mineral acids were studied. The relative 1H and 2H relaxation rates in solutions of equal compositions and concentrations were compared. Bringing the proton and deuteron resonance data into consistency was shown to require the introduction of corrections for changes in the quadrupole coupling constant of deuterons present in different solution substructures. The experimental estimates of the deuteron quadrupole coupling constants in the D3O+ ions and the hydration shells of the D3O+ and SO4 2- ions were compared with the results of quantum-chemical calculations.
