WebAbsorption is the fact that the intensities of the measured reflections are reduced because the diffracted beams are absorbed when travelling through the crystal. If our crystal was a perfect sphere, then this wouldn’t matter: All diffracted beams will have to travel through the same length through the crystal (assuming that diffraction ...

Webρcalc = ρobs - Δρ therefore for acentrics: ρcalc = F(2mFo-DFc) - F(2(mFo-DFc)) = F(DFc) whereas for centrics: ρcalc = F(mFo) - F(mFo-DFc) = F(DFc) Hence the correct Fourier coefficient for ρ calc is DF c for all reflections.
