Zeeman ( \(T_{1 Z}\) ) and dipular ( \(T_{1}\) ) spin-latice relaxation times of proicns in \(\mathrm{NH}_{4} \mathrm{H}_{2} \mathrm{AsO}_{4}\) were measured as a function of temperature The evistence of a slow motion \(\left(\tau \approx 10^{-3}\right.\) sec) is sstablished, which is niost probably
The ground toaioncd Ievei structure of NH; in ammonium perrhenate (NIQRe04) has been analysed by a study of its proton magnetic resonance lineshape 51 the polycrystalhne state at 4 K. It is shown that, in this structure, tunneilin~ rotation of NH: around one of its C2 axes is greatly favocred over t
Librational tunneling levels of NH, + ions in an (NH,),SnBr, single crystal were determined by studying the proton Zeeman relaxation. The relaxation rate speeds up when any of the tunnel frequencies vI equals n va (n = f , 1, 2). where v0 is the proton resonance frequency. The energy separation betw
Nuclear spin-lattice relaxation times T, for protons in polycrystalline (NH4)2GeF6 were measured by the NMR pulse method from room tempersture to liquid helium temperature at 8 MHz and at 52 MHz. An anomalous temperature dependence of T1 WIS observed below LS'K at 8 hlHz. Parameters of the reorienta
