Spectral changes for a binuclear complex with longer equilibrium Cu–Cu distance. (a) Low sensitivity to the Cu–Cu distance of k2-weighted χ(k) in the range 1.5–6.5 Å−1. (b) Variation of the C—H bending frequency of triethylamine ligands as a function of Cu–Cu distance. The C—H bending mode is denoted with dashed orange arrows. |
