The SPECSY group investigates solid-liquid interfaces by a combination of electronic structure modelling and experimental optical spectroscopy. The aim is to understand on an atomistic level the structure of electrochemical interfaces as a function of the potential applied to the electrode. We address the challenge to convey this information through the liquid electrolyte in a time-resolved manner by employing the highly interface-sensitive optical technique reflection anisotropy spectroscopy in electrochemical environments. The experimental spectra are then interpreted with the aid of computational spectroscopy on top of an electronic structre from density functional theory. Our approach will help to understand ion adsorption and corrosion processes in solar fuel devices and batteries.
