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
The proton NhlR spectrum of NH4PF, at 77 I: remains narrow even under a pressure of 14 kbar. The barrier for PFZ reorientation at 14 kbar is higher than the value at 1 bar. The asymmetry of the t9F spectrum at 77 K increases with pressure. The possibility of inequivalent chemical shifts of the 19F n
