Ammonium Compounds 27-45 spindlin 1 Homo sapiens 0-4 29126075-3 2017 The 1H spin-lattice relaxation times of the acid protons decrease with increase in the content of ammonium ions. Ammonium Compounds 98-106 spindlin 1 Homo sapiens 7-11 29126075-7 2017 Spin diffusion between the acid and the ammonium protons averages partially the 1H relaxation of the acid and the ammonium protons at the MAS rate of 8 kHz. Ammonium Compounds 40-48 spindlin 1 Homo sapiens 0-4 29126075-14 2017 Using those parameters, the effect of ammonium ions on the 1H spin-lattice relaxation can be predicted. Ammonium Compounds 38-46 spindlin 1 Homo sapiens 62-66 29126075-15 2017 The 1H spin-lattice relaxation is a sensitive tool to study the distribution of ammonium ions in solids. Ammonium Compounds 80-88 spindlin 1 Homo sapiens 7-11 29126075-0 2017 Spin diffusion and 1H spin-lattice relaxation in Cs2(HSO4)(H2PO4) containing a small amount of ammonium ions. Ammonium Compounds 95-103 spindlin 1 Homo sapiens 0-4
