The admittance of the interface between a metal electrode and an aqueous electrolyte solution: some problems and pitfalls.

Electrochemical admittance measurements have become popular as a convenient, non-invasive method for the study of interfacial properties of the metal-solution interface. However, uncritical use of this technique (as of any other) can lead one astray. Here, then, some of the complicating factors and common problems will be discussed.
