High-resolution ellipsometric studies on fluid interfaces
Résumé
In this article, highly accurate experimental results reveal the interfacial profile between different macroscopic fluid phases. The deviation from a step profile, quantified by the ellipsometric quantity J1, shows a strong correlation with the cohesive energy quantified by the Gordon parameter G. Surprisingly, at high values of G, J1(< 0) deviates significantly from any predictions. Findings for water and water-like interfaces can be interpreted in terms of the strength of hydrogen bonding at the surface.
