Chemical shift, Δ E , of the X‐ray K‐absorption edge is measured in some compounds and organometallic complexes of copper possessing formal oxidation states 1 + and 2 + . The best fit correlation between the chemical shift, Δ E , and the effective charge, q , using the least‐squares regression analysis procedure is found to be a non‐linear equation Δ E = Aq + Bq 2 + Cq 3 , where A, B and C are constants. In the light of statistical treatment it is shown that the effective charge, q , is a significant explanatory factor of the variation in the X‐ray absorption chemical shift, Δ E . Interpretations to the variations in X‐ray absorption chemical shift are also given on the basis of electronegativity, oxidation state, the valence d‐orbital electrons, atomic number, crystal structure, etc.
