A method is presented for analyzing satellite reflections in X‐ray diffraction patterns in terms of two‐ or three‐dimensional atomic ordering arrangements. The ordered arrangement of Nd atoms in Nd 2 (MoO 4 ) 3 has been successfully determined by this method. The derived model is consistent with the observed location and intensity distribution of the satellite reflections, as confirmed by structure factor calculation and by optical diffraction.
