Research Project at UAB
In this program, the group will work in close contact with the experimental teams of the MCRTN to develop the following project:
COMPUTATIONAL MODELLING OF AQUEOUS ORGANOMETALLIC CHEMISTRY
Theoretical studies can give accurate measures at the molecular level, but until recently in the organometallic field they have been usually limited to model compounds with small ligands and to gas phase conditions. The recent development of hybrid quantum mechanical/molecular mechanics (QM/MM) techniques and the introduction of solvent models has allowed computational methods to approach to the real organometallic world. The extension of these studies to an aqueous environment will be the main goal of this project. Work will be done in close collaboration with the experimental groups involved in the AQUACHEM network. The project includes the computational study of hydrogen bonding interactions between solvent molecules and ligand or metal centers, mechanistic studies of water exchange and proton transfer processes, with characterization of reaction intermediates and transition states, and the modelling of catalytic cycles in aqueous media.
The project is destined to a Postdoctoral fellow. Applicants should have a good experience in theoretical organometallic chemistry and good knowledge of the ab initio/DFT methodologies. They should be familiar with standard program systems and should be interested in applying theoretical chemistry as a tool to analyse, understand and guide experimental chemistry. Familiarity with QM/MM methodologies and solvent methods are also desirable.
