Scientific Interests


The use of the modern computational methods of quantum  chemistry to study organic chemistry and transition metal organometallic chemistry.
Molecular orbital calculations are used to study molecular structure and reactivity problems. The geometric changes driven by electronic structure modifications on the molecules may be rationalized from the molecular orbital results. For example, in an organometallic complex, some ligands may adapt their coordination mode to the metal as a function of the total electron count on the coordination sphere. This can vary by means of a reduction or an oxidation of the molecule, or by ligand addition or elimination, in processes that take part in many relevant organometallic reactions, such as catalytic reactions. Computational chemistry studies have been used to provide an important contribution to the fully understanding of those problems.
Computational methods are also used to study mechanistic and reactivity problems, allowing the detailed analysis of very unstable species, such as intermediates or transition states, and providing information that cannot be obtained by experimental studies. The results provide a detailed picture of the reaction path and the corresponding energetic, and may be used to tailor improved reaction methods. 


Computational methods

The electronic structure is studied by means of ab initio and DFT molecular orbital calculations complemented with populational and orbital analysis that can provide usefull chemical interpretation to the quantitative 'crude' results of the calculations (geometries and energies).
