| pubmed-article:15225041 | pubmed:abstractText | We report the first observation of 77Se nuclear magnetic resonance (NMR) in octaneselenol-protected Au nanoparticles of an average particle size of 2.5 nm. The 77Se NMR characteristics observed, i.e., broad line shape, fast nuclear spin-lattice, and spin-spin relaxation rates, which are reminiscent of 13C NMR of CO on transition metal surfaces, strongly suggest that Se becomes metallic upon binding to the Au nanoparticle surfaces. | lld:pubmed |
