A molecular view of the water interface — •Yuki Nagata and Mischa Bonn — Max Planck, Mainz, Germany

Water surfaces and interfaces are ubiquitous, not just in nature, but also in many technological applications. Water is a rather unique liquid, owing to its strong intermolecular interactions: strong hydrogen bonds hold water molecules together. At the surface of water, the water hydrogen-bonded network is abruptly interrupted, conferring distinct properties on the interface, compared to bulk. I will present some challenges and progress in the study of interfacial water. Specifically, I will address how to study the ∼1 monolayer of water molecules that is in direct contact with the other phase, and distinguish this ∼Angstrom-thin layer from the bulk. The question rises how large the interface is. And can we describe the interfacial region as a modified dielectric continuum, or do we need to consider molecular structure?
