It has been believed that the short-range correlations of the methylammonium (MA) cations impact the high photovoltaic efficiency of the hybrid organic/inorganic halide perovskite. Employing high-resolution THz spectroscopy technique and solid-state density functional theory method, we have revealed new evidence on 16 correlation patterns of MAs in the MAPbBr3 crystalline system. By integrating the current structural information provided by other analysis methods, we have suggested a fine-structure model for the halide perovskites.
