Experimental and Computational Aspects of Electrochemical Reflection Anisotropy Spectroscopy: A Review

Electrode/electrolyte interfaces play a crucial role in many electrochemical energy conversion and storage technologies. Hence, deep understanding of the interfacial structure, energetic alignment processes is high relevance has triggered development number situ operando techniques. One approach for gaining information about change surface chemistry structure on an atomic scale reflection anisotropy spectroscopy (RAS). This review presents discusses continuing effort to develop RAS as optical probe solid-liquid under applied potentials. Experimental computational basic principles are presented key challenges highlighted. Furthermore, we exemplarily demonstrate potential method spectroelectrochemistry, focusing indium phosphide- gold-aqueous electrolyte exemplary case studies, outline research directions battery systems.
