    • For a three-body signal, the GNXAS program uses a first-order Taylor expansion of the amplitude and phase to calculate the configurational average of the signal. In the case of a linear structure (θ = 180°), the first-order derivative vanishes and therefore second-order derivatives are used. In the nearly linear oxo bridge, the effect of thermal vibrations was modeled either as a Gaussian distribution around a slightly bent average configuration or as a vibrating collinear configuration. In the latter case, the average deviation from 180° is measured by the angle variance, as described in ref 23. Fits which varied the Fe-O-Cu angle around 175.3° (with the upper limit to be 178°) as well as fits which included a fixed angle of 180° were carried out. The two methods were found to give fits of similar quality and results, indicating that GNXAS is quite reliable in fitting linear structures.

    • 1 state to be more intense. Thus the 1s → 3d preedge feature of the oxo-bridged complex will be more intense than that of the hydroxo-bridged complex due to the shorter Fe-O bond distance/more distorted site. The methodology describing the allowed many-electron excited states and the distribution of quadrupole and dipole intensity over those states is described in much more detail for high-spin and low-spin ferrous and ferric complexes in the following: Westre, T.
