Proton magnetic relaxation in (TMA)2HgBr4 and (TMA)2HgI4

Abstract

Abstract. Internal motions of the protonic groups have been studied in polycrystalline [(CH3)4N]2HgBr 4 and [(CH3),~N]2HgI4 from the temperature dependence of proton spin relaxation time (T~) and the data analysed according to the spin lattice relaxation model due to Albert and coworkers. The temperature dependence of T~ in the above compounds is compared with that in (TMA)2HgCI4 and (TMA)2ZnCI4.
