Baffle

Accurate Studies on the Structure and Reactivity of Transition Metal Complexes and Clusters,CuH.O and Ni(C.H.). with n=1, 2. The final application is concerned with the modelling of chemical reactions on transition metal surfaces. A strategy for choosing a proper effective core potential for the metal atoms is outlined. Preliminary results for O. dissociation on nickel clusters are presented.

Correlation Effects in the Ground and Ionized States of Transition Metal Complexes,of bis(π-allyl)nickel have been compared with the ionization energies calculated using the extended-two-particle-hole Tamm-Dancoff method, which includes both relaxation and correlation effects. For all species studied, excellent agreement between theory and experiment is found, which, for bis(π-allyl)nickel, is absent for ASCF-CI calculations.

Quantitative Results and Qualitative Analysis by the Hartree-Fock-Slater Transition State Method,extensive calculation schemes by forcing them to provide a qualitative analysis of the-(at best) quantitative results, and we present here a scheme, the generalized transition state method., by which quantitative (or at least extensive) calculations can be subjected to a qualitative analysis.

Accurate Studies on the Structure and Reactivity of Transition Metal Complexes and Clusters,of calculated binding energies. For NiH and NiO. comparison is made to molecular beam experiments. For NiCO. and NiCO comparisons are made to measurements of appearence potentials in fragmentation experiments. In the second application comparisons are made to matrix isolation experiments for NiH.o,

The Electronic Structure of Transition Metal Atoms and Diatoms Through Pseudopotential Approaches,terrelated points of view, namely relativistic effects, correlation contributions and possible pseudopotential approaches. The relativity impact is approached by comparing results obtained through pseudopotentials including or not mean relativistic terms. Special emphasis is put on the interplay bet

Spectroscopic Characterization of Bonding in Diatomics and Small Transition Metal Aggregates,hase aggregation or matrix isolation in solids at low temperature. The second part describes the spectroscopic methods involved in the characterization of such species with their possibilities illustrated by some results obtained in this field. We tentatively show how these techniques are yielding n
