Abstract
The technique of second-harmonic a.c. polarography is discussed from the viewpoints of theoretical basis, experimental requirements, and scope of application. The theoretical relation is given for the second-harmonic current-component of a straightforward electrochemical reaction under conditions of a.c, polarography. It is shown how this relation can be used to determine the kinetic parameters (rate constant and transfer coefficient) of the electron-transfer step. Results obtained with the zinc(n)/zinc (mercury) system are in good agreement with those reported in other investigations by other methods. The experimental aspects of second-harmonic studies are examined, and the dependence of the accuracy and reliability of results on various features of the instrumental arrangement is brought out.��� Potential applications, particularly in tensammetric studies and in analytical work, are indicated.
