Copyright 1989 Durand, Dale James Physics, Condensed Matter Nuclear magnetic resonance study of quantum size effects in supported platinum particles text Slichter, C.P. Durand, Dale James 2011-05-07T11:52:23Z 2011-05-07T11:52:23Z 10000-01-01 1989 The author has observed, and studied quantum size effects in the NMR of small, supported platinum particles with a monolayer of carbon monoxide chemically adsorbed to the surface. The effects are observed in the $\sp{13}$C and $\sp{195}$Pt NMR, primarily at 4.2K. He reports nonmetallic spin-lattice relaxation, and changes in the Knight shift at low temperatures. He shows that the variation of the quantum size effects at 4.2K with particle size is consistent with a prediction based on simply scaling the bulk density of states at the Fermi energy with the volume of the particles. An interpretation is proposed based on the relative sizes of the electron Zeeman energy and the level spacing of particular particles. Made available in DSpace on 2011-05-07T11:52:23Z (GMT).
