| Abstract: | Internal motions of the protonic groups have been studied in polycrystalline (CH3)4N]2HgBr4 and (CH3)4N]2HgI4 from the temperature dependence of proton spin relaxation time (T 1) and the data analysed according to the spin lattice relaxation model due to Albert and coworkers. The temperature dependence ofT 1 in the above compounds is compared with that in (TMA)2HgCl4 and (TMA)2ZnCl4. |
