The goal in this work has been to experimentally examine the effect of the presence of citrate-stabilised Au NPs on the solvation shell water. Having an extensive network of easily perturbed hydrogen-bonding, liquid water manifests significant changes in vibrational spectroscopic response, stemming from structural changes that lead to changes in water intermolecular interactions. Therefore, vibrational spectroscopic tools can be expected to present a powerful window to study water structure. In this work, Raman spectroscopic methods were implemented to achieve the goal.
