摘要：

Anomalous X-ray scattering effects are quite extensive in the noncentrosymmetric ferroelectric structure of barium titanate, and typical estimates for three published X-ray diffraction experiments are computed. These data show that the Bijvoet pairs should not be averaged before least-squares refinement for this polar crystal with small atomic displacements from a higher symmetric space group.
