Abstract
$^{1}\mathrm{H}$ NMR static, and rotating-frame spin-lattice relaxation times and dipolar relaxation times were measured between 135 and 270 K for a single crystal of ammonium dihydrogen phosphate. Random fluctuation in nuclear dipolar interactions by means of ammonium-ion reorientation was found to be the dominant relaxation process. A critical fluctuation contribution to relaxation near the paraelectric-antiferroelectric phase transition, which was postulated in a previous study, was found to be unnecessary to account for the relaxation-time results.
