Kramers-Kronig Transforms of the AC Impedance and Their Applications to the Inhibitors of Copper Electrodes

The availability of Kramers-Kronig transforms to the data of alternating current impedance of the electrochemical system has been discussed on the basis of the theory of analytical functions. Kramers-Kronig transform may be used as criteria of the linearity and stability of the system. For systoms suitable to K-K transform the K-K transform will show the reliability of the data obtained by experiments and be means of diminishing errors in measurements. The approximate calculation of numerical integrals using forty data of seven decades has been established and proved to be accurate and useful. The results have been applied to inhibitors of copper electrodes with success.
