“…In particular, the interaction between nanocolloids and water is expected to be very weak and short-ranged, because it should be governed by forces of the dipole-induced-dipole type. The few studies of the SERS effect on water reported hitherto, 17,18 could be the consequence of these weak interaction forces.…”

Weak interactions, never reported yet, between silver nanocolloids and water, have been studied by Raman spectroscopy in the O-H stretching region. Subtle interactions regarding the first hydration shell, and perturbing only at a short range the bulk liquid structure of the solvent have been revealed. The interface interactions cause the O-H stretching band of water in the interface layer spectrum to be shifted at higher wavenumbers with respect to the neat water Raman signals. Order/disorder ratio variations, with respect to the liquid spectrum of pure water, are reported.

“…Further evidence for the existence of two discrete water types appears in the l(OÈH) region, which is the subject of a detailed presentation in the following paper. 34 Two other features of the SERS data are noteworthy. First, the intensityÈpotential dependence is reversible, strongly suggesting that unique Ag surface sites play a minimal role in the overall response.…”

Br~surface coverage as a function of electrode potential is quantitatively determined using the HurwitzÈParsons analysis of di †erential capacitance data at Ag electrodes in the series of normal alcohols, methanol through pentanol, containing LiBr. Values for the potential of zero charge (pzc) are estimated from these data. Surface-enhanced Raman spectroscopy (SERS) data in the l(AgÈBr) region show the presence of a l(AgÈBr) feature at potentials positive of the pzc which supports strong speciÐc adsorption of Br~in these media. An excellent correlation between the SERS intensity and the Br~surface coverage determined from di †erential capacitance is observed. Bands attributed to hindered translational modes of trace interfacial water are also observed.

“…In nonaqueous systems [87], the amount of water is very limited, coming from trace water that remains after purification of these solvents or from water intentionally added to the solvent. The extensive hydrogen bonding of bulk water is broken, resulting in ν O−H bands of greater resolution than observed in aqueous media.…”
