Probing liquid surfaces using reactive-atom scattering
Probing the composition and structure of the outer surface of a liquid is a challenging but important problem, with implications for many real-world processes in the atmosphere, multiphase catalysis, and gas sequestration. It has been tackled using a number of conventional surface-science and surface-spectroscopy tools, but these all have their own limitations of excessive penetration depth or lack of chemical specificity. We are developing a promising new method, reactive-atom scattering, which is based on laser-spectroscopic detection of the products of the reaction of a gas-phase projectile with a specific functional group at the surface. We have demonstrated that the relative yields of the product reflect the exposure of this functional group at the extreme outer layer of the liquid. We are pursuing this method to probe the surface composition of chemically heterogeneous liquids where it is not obvious, particularly technologically important ionic liquids, their mixtures and solutions.
