Nonlinear spectroscopy and interfacial structure and dynamics

The ubiquity and importance of surfaces and interfaces can hardly be overstated. They play a central role in processes ranging from atmospheric/environmental chemistry and biological function to electrochemistry, heterogeneous catalysis, and solar energy conversion. Surface-specific nonlinear optical techniques have a unique advantage of being able to probe buried interfaces between condensed phase media that are inaccessible otherwise. In combination with theory and computer simulations, they enable a unified approach to studying underlying physical phenomena at a wide variety of interfaces from the same standpoint, including liquid/liquid and wet/soft interfaces as well as solid surfaces. This Special Issue is a collection of papers that attempts to represent the modern state of research in this rich and diverse field.
