This study investigates the hydrogen-bonding structure of water in the solvation shells of various nanoparticles (Ag, Au, ZnO, TiO₂) using Raman multivariate curve resolution (Raman-MCR) spectroscopy. To assess the influence of localized surface plasmon resonance (LSPR) on the spectral analysis, finite element method (FEM) simulations with JCMsuite were performed. These simulations calculated the electric field intensity enhancement around isolated nanoparticles, helping to interpret how the proximity of the laser wavelength to the particle's LSPR affects the magnitude of observed spectral differences between bulk and interfacial water.
