In order to investigate the dynamics of the ZnCl4 tetrahedra in K2ZnCl4,35Cl nuclear quadrupole resonance was employed for the spin-lattice relaxation measurements of each of the triplicated Cl sites in the lock-in phase. The temperature dependence of the spin-lattice relaxation rate (1/T1Q) indicates that the domain peak observed in the incommensurate phase arises from the ZnCl4 tetrahedral site with a negligible reorientational motion. On the other hand, an activated reorientational motion of the other two ZnCl4 tetrahedral sites appears to lead to the phase solitons. Molecular motions in Rb2ZnCl4 and in Cs2ZnCl4, undergoing an incommensurate an not incommensurate phase transition, respectively, were also compared.
