This course aims to initiate the chemistry students to the essential of quantum chemistry and its application to theoretical and/or model chemistry. It is not limited to formal teaching, but includes an introduction to the practice of the discipline by discussing some carefully chosen examples.
Main themes
Introduction to the formalism of quantum chemistry. Presentation of mono and multi configuration methods followed by their use in the computation of structural, electronic and energetic molecular properties, including the search of reaction mechanisms.
Content and teaching methods
Content
- Concepts and methods of current use in molecular and chemical modelling are presented: A short introduction to the formalism is given. Keywords: Orbital model; Hartree-Fock method; Roothaan LCAO-SCF MO expansion, Configuration Interaction, Molecular properties.
- Applications: Potential energy surfaces are discussed and analysed in relation to the molecular structure of isolated molecules. Discovering isomers, conformers and other stationary points on the surface leads to evaluate the relative energies and transition barriers involved by structural changes of a molecule. A reaction pathway can be deduced from considering interacting molecules.
- A selected example is explicitly studied with the aid of quantum chemical computation software: Keywords: Obtaining a structure; analysing the electron distribution and charge population; imaging electron densities and their reorganisation;
