Résumé :
The collision-induced dissociation (CID) of transition metal carbonyl clusters have been recorded and presented using the recently developed technique of energy-dependent electrospray ionisation mass spectrometry (EDESI). EDESI has been improved to incorporate breakdown graphs, allowing complete fragmentation data to be presented. EDESI spectra facilitate the assignment of all ligands, and assist in determining the composition of the cluster core. Electron autodetachment was observed upon ligand loss from multiply charged clusters. For certain clusters, a remarkable amount of structural inform

Résumé :
Early transition metal oxide clusters have been a focus of study for several years. The production of vanadium oxide cluster anions in a pulsed helium flow reactor provides a relatively precise way of introducing defect sites and controlling the oxidation state of the vanadium atoms. The composition of the clusters can be changed from the V2O5 stoichiometry, where the vanadium atom is in a +5 oxidation state, to more reduced stoichiometries yielding a mixture of oxidation states containing atoms in the +2 oxidation state. The subsequent addition of reactant gases such as H2O and SO2 yields

The factors which govern the applicability of the "surface-cluster analogy" are examined, and structural comparisons between organic species chemisorbed on the metal surface and similar ligands bound to metal clusters are used to develop these ideas. Particular reference is made to chemisorbed ethene since the bonding modes of this ligand are of most relevance to subsequent chapters.
