Buried solid–liquid interfaces constitute the primary stage of electrochemical reactions, and operando vibrational spectroscopic probing of these interfaces is essential for advancing the performance and durability of electrode materials. To date, surface-enhanced Raman spectroscopy and vibrational sum-frequency generation spectroscopy have been widely employed. However, their applicability is often limited by constraints on accessible sample configurations and reaction environments. In this study, we develop a coherent Raman spectroscopy scheme incorporating simultaneous spatial and temporal focusing, which enables versatile operando measurements of buried solid–liquid interfaces under realistic electrochemical conditions. Detailed experimental results and discussion will be presented at the conference.
