Figure 1 Schematic representation of the relevant absorption coefficients in a diffraction experiment. The four different coefficients are [1] for absorption in the crystal, [2] for absorption in the mother liquor surrounding the crystal, [3] for absorption by the nylon loop used and [4] for absorption in air (or helium).
