Single-crystal XRD is normally more sensitive to weak reflections than powders. However, conformation is still needed when we conclude a weak forbidden reflection, because λ/2 contamination of the X-ray source and multiple diffraction effect are usually unavoidable, e.g. for inorganic single crystals. The overlapping problem of powder X-ray diffraction (PXRD) can be partially solved through the fast iterative Patterson squaring (FIPS), [1] repartitioning by histogram matching in a charge-flipping algorithm [2] or other methods.
