UV contribution and power dependence on ${\mathrm{\Lambda }}_{\mathrm{Q}\mathrm{C}\mathrm{D}}$ of Adler function

We formulate a way to separate UV and IR contributions to the Adler function and discuss how ${\mathrm{\Lambda }}_{\mathrm{Q}\mathrm{C}\mathrm{D}}^2\mathrm{/}{Q}^2$ dependence is encoded in the UV contribution within perturbative QCD.
