This book experimentally demonstrates how plasmons, a type of polariton that has recently attracted attention, modulate molecular motion, chemical properties, and chemical reactions. It is shown that the localized electric field generated by plasmons not only retards the 2D diffusion of adsorbed molecules but also forms a unique molecular adsorption state as a dissipative structure under light illumination. Furthermore, Raman spectroscopy suggests that the energy state of the interfacial molecules is modulated by charge transfer resonance under the specific Fermi level controlled by the electrochemical potential. In addition, results that actually modulate the electrochemical reaction without specific resonant light as evidence for polariton coupling with molecules as a dark state are described.

This book provides basic insights into polariton chemistry, especially in electrochemical reactions. It also proposes an innovative approach and bridges the physical principle and advanced science for innovative reaction control.
