The Bijvoet difference between the amplitudes of Friedel mates depends on the difference between the phase of the normal scattering vector of the anomalous atoms, φA, and the phase of the average total structure factor, 〈φT〉. If these two phases differ by 90°, the Bijvoet difference is the largest possible; if they differ by 0 or 180°, no Bijvoet difference is observed. |
