Abstract: We have investigated the metal-insulator transition (MIT) of CuIr2S4 by a high resolution NMR measurement. The Cu-NMR spectrum below T MI is broadened and split into four Cu signals with sizable electric quadrupole interactions. The NMR results are consistent with the charge ordering of Ir^3+ and Ir^4+ and the spin dimerization of Ir^4+ spins, as revealed by a recent X-ray study.
