Comparison between the X-ray mass attenuation coefficients of (i-pr Ni) (red) and (n-pr Ni) (black) measured using the intensity measurements with 15 mM solutions of each of the complexes (isomers). The impact of the conformation change is dramatic and easily observed. The green solid line shows the tabulated theoretical values (FFAST; Chantler, 2000BB5) with no oscillations. Notice that at high energies there is an offset between the solutions. This is because the relative uncertainty has been plotted but the uncertainty in absolute scaling is dominant and is about 1%. We plot the relative uncertainty because this is the relevant uncertainty for XAFS analysis in the sequel paper.
