In this study, we experimentally investigated remote plasmon-molecule resonant coupling in remote-plasmonic enhanced Raman scattering (RPERS). The results revealed that RPERS strongly depends on plasmon activity and is likely driven by resonant coupling with molecules, as indicated by its wavelength and molecular concentration dependencies. These findings demonstrate a new possibility for plasmon-molecule interactions and contribute to the expanded application of molecular photonics.
