An assessment of the current slate of models of the inner part of the metal/electrolyte interphase is made with particular reference to theadsorption oforganicmolecules. Recent developments, both theoretical and experimental, have indicated defects in the models used up until recently. Improved mode

β¦ Synopsis
The adsorption of thiourea on gold has been investigated as a function of potential and concentration, using a radiotracer method. The behaviour of the system is interpreted in terms of a simple molecular model. The distribution of potential in the double layer and the dominant energetic factors governing adsorption, viz., chemical binding energy, field-dipole interaction, distortion of the double layer and lateral interaction have been evaluated and are discussed.
