Characterisation of small Metal Particles

2 Characterisation of Small Metal Particles. - Some aspects of 

An example of a larger cluster which is not typical of a bulk metal is provided by [Rh S2(CO) 2J - Even though this anion still has high symmetry there is a greater multiplicity of 

Since some of these shells were characterised by parameters with high correlation coefficients it is unlikely that more than 9 of these distances would have been resolved if analysing an unknown system (IRh-S, IRh-Rh and lRh..Rh shells would probably be missed). This would not be sufficient to identify the entire cluster, without any substantial corroborating evidence. Nevertheless, significant information about such a unit would be evident, viz the 

Larger metal arrays of the type considered to be present in many supported metal catalysts may also be usefully studied by EXAFS. Firstly, the packing form of the array can generally be 

Os on silica was considered to adopt a disc morphology but 19A Cu on the same support consisted of spherical particles.
