摘要：

Cation dynamics in tris(trimethylammonium) nonachlorodiantimonate, which shows different phases as a function of temperature, is studied through proton spin lattice relaxation measurements at five Larmor frequencies. Results show a clear signature of the para-ferroelectric phase transition at 363K and the existence of dynamically inequivalent trimethylammonium cations and methyl groups, both in the ratio of 1:2. Various activation energies associated with the dynamics of the cations and methyl groups are calculated.
