Response properties for valence bond wavefunctions: theory and applications to transition metal complexes.

Samenvatting

The study of transition metals using ab initio techniques is proposed in order to find relationships between the (electronic) structure, the molecular properties and the chemical reactivity. The chemical reactivity of the transition metal complexes will be studied by calculating their potential energy surfaces, and the location of the minima and saddle points, thus a detailed study of the different possible reaction pathways will be performed. The stationary points obtained will be subjected to a detailed analysis of their electronic structure and molecular properties. The use of valence bond theory for this analysis will offer new insights in the bonding of these complexes. The development of a new response property code for valence bond wavefunctions allows the establishment of the still unknown relation between the molecular properties and the bonding situation in the complex.
The combined study of reaction mechanisms, potential energy surfaces, chemical bonding in terms of valence bond structures, and molecular properties will reveal new fundamental knowledge about transition metal complexes, which can be used in understanding their chemistry. This will for example help in the improvement of existing and the design of new catalysts, based on transition metals.
