In recent years, vibrational strong coupling states, which emerge through a photo quantum interaction between vacuum fields and the vibrational modes of matter, have garnered attention as a method for controlling electrochemical reactivity. In this study, to explore the application of vibrational strong coupling states to interfacial electron transfer reaction systems, simulations were conducted using the finite-difference time-domain (FDTD) method based on interfacial structural designs exhibiting plasmonic surface lattice resonance (SLR). The study aimed to identify optimal structures capable of forming vibrational strong coupling states, focusing on water molecules that play a significant role in electrochemical reactions.
