The resonance frequencies and relaxation mechanisms of Cs2CuBr4 and Cs2ZnBr4 were examined by static nuclear magnetic resonance (NMR) method. Here, the two inequivalent Cs(1) and Cs(2) sites surrounded by Br ions were distinguished. The saturation recovery traces for 133Cs nuclei in Cs2CuBr4 with the paramagnetic ions, and those in Cs2ZnBr4 without the paramagnetic ions were each fitted by four exponential functions. From these results, the spin–lattice relaxation times T1 in the laboratory frame of 133Cs nuclei in the two crystals were obtained, and Cs(1) surrounded by 11 bromide ions has a longer relaxation time than Cs(2) surrounded by 9 bromide ions.
