(IUCr) Local structure in molecular complexes

Figure 4
MS irreducible $[\gamma^{(2)}]$ , $[\gamma^{(3)}]$ and $[\gamma^{(4)}]$ Cu K-edge XAS signals associated with a four-body chain-like Fe-C-N-Cu configuration. The total effective four-body signal $[\eta^{(4)}]$ is given by the sum of the n-body signals involving the fourth atom of the fragment (Fe). The results of the calculations for $[\theta_2=\theta_{\rm CNCu} = 120]$ ° and 180° are reported in the left-hand and right-hand panels, respectively.
