Properties and reactions of molecules at interfaces I. Theoretical remarks on ionic concentrations in the neighbourhood of monolayers containing charged groups)

The calculation of the electric potential and the ionic concentrations in the neighhourhood of a monolayer containing fatty acids or other, partially ionized, organic acids is discussed in order to get a basis for the understanding of reaction rates in unimolecular layers. The systems tinder connsideration show several features allowing straightforward theoretical reasoning. It seems difficult however to reach a detailed description without further experimental study. Therefore a simplifying treatment using the well‐known Gouy‐Chapman method is deemed to he acceptable at this stage to serve as a lead in experimental research.
