Abstract

We have used synchrotron radiation to study the highest pressure phase of Langmuir monolayers of heneicosanoic acid in the presence of copper and calcium ions in the subphase. We see structural changes as a function of pH, correlated with previously reported changes in the chemical composition of the monolayers. The diffraction data show the same trends in both cases, except at pH values near the hydroxide precipitation regions.
