摘要
Clusters consisting of [AU(3)SC(8)H(17)](2+) and [AU(5)Cl(4)SC(8)H(17)] are employed in ab initio shielding calculations to model octanethiols adsorbed on the surface of gold nanoparticles. The isotropic shielding and its principal components are calculated using the coupled Hartree-Fock gauge-including atomic orbital (CHF-GIAO) method. The computed values compare favorably with those observed in solid state nuclear magnetic resonance (NNR) measurements of octanethiol-coated gold nanoparticles. (C) 2002 Elsevier Science B.V.
