Up to now the influence of capping has been included as a phenomenological modification of the scattering constant. It is indicated here that the effective NP size is the parameter mainly affected by surface bonding. Experimental results in different Au-thiol NPs are shown to be in excellent agreement with the expression we propose for damping. Moreover, according to our model the resonance profile gives a deep insight of the interface bonding strength.engSurface plasmon resonance of capped Au nanoparticlesjournal articlehttp://dx.doi.org/10.1103/PhysRevB.72.241403http://journals.aps.orgopen access538.9Absorption-spectraGold nanoparticlesNanocrystalAdsorptionMoleculesClustersColloidsSystemFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
