Estimation of signal size. The expected Bijvoet ratio is r.m.s.(ΔF±)/r.m.s.(|F|) ≃ (NA/2NT)1/2(2f′′A/Zeff). The expected dispersive ratio is r.m.s.(ΔFΔλ)/r.m.s.(|F|) ≃ (NA/2NT)1/2[|f′A(λi) - f′A(λj)|]/Zeff, where NA is the number of anomalous scatterers, NT is the total number of atoms in the structure and Zeff is the normal scattering power for all atoms (6.7 e− at 2θ = 0). |
