- W2006922142 abstract "Abstract Chlorine NQR frequencies, and NQR spin-lattice and spin-spin relaxation times (T 1Q and T 2Q ) were measured for NH 4 AuCl 4 crystals at various temperatures between 4.2 and 337 K. Each of the two resonance lines observed at room temperature is split into a doublet below T c = 29 K, indicating a phase transition. A rapid decrease of T 1Q above ca. 290 K is attributable to 90° reorientational jumps of the complex anion about its pseudo C 4 axis. An activation energy of 80 kJ mol -1 was obtained for this motion. 35 Cl T 1Q exhibits a minimum at T c . The T 1Q isotope ratio T 1Q ( 37 Cl)/ T 1Q ( 35 Cl) becomes 1.6 and 1.0 on the high-and low-temperature sides of this minimum, respectively. These results were explained by fluctuations of the electric field gradient produced at the chlorine nuclei by the reorientational jumps of the NH + 4 ions. The motion of the cations is much faster and much slower than the resonance frequencies on the high-and low-temperature sides, respectively. This suggests that the phase transition is of the order-disorder type relating to the orientation of the NH + 4 ion." @default.
