General angular momentum theory.
The central field problem.
Time-independent perturbation theory and variation theory.
Born-Oppenheimer approximation and molecular potential energy surfaces.
General operator properties and the antisymmetrizer of the permutation group.
Many-electron theory (Slater determinants and Slater-Condon rules).
Hartree-Fock-Roothaan theory for self consistent treatment of molecular electronic states.
Methods for describing electron correlation: Configuration Interaction (CI), Møller-Plesset perturbation Theory (MP2), Coupled Cluster (CC) and Density Functional Theory (DFT).
Molecular interaction with external electric fields by means of perturbation theory.
The overall goal of the course is to make students able to
understand and handle the quantum chemical description of
many-electron systems like atoms and molecules. In completing the
course the student is expected to have acquired
After the course the student should be able to:
- Explain and use fundamental quantum chemical conceps like probability densities, commutator relations.
- Derive the eigenvalue spectrum for general angular momentum operators and apply the result in connection with the description of atoms and molecules.
- Explain the variation principle and to derive the linear variation method and the time-independent perturbation theory.
- Formulate the Pauli principle for many-electron sytstems.
- Discuss determinantal electronic wavefunctions.
- Derive and use the so-called Slater-Condon rules for the evaluation of expectation values over many-electron operators.
- Derive the Hartree-Fock equations and explain the Brillouin's and Koopmans' theorems.
- Explain Roothaan's equations and their use in electronic structure calculations.
- Discuss the contents of Density Functional Theory and correlated methods like Configuration Interaction, Møller-Plesset Perturbation Theory and Coupled Cluster.
- Apply perturbation theory in the calculation of electric polarizabilities of atoms and molecules.
- Explain the quantum chemical description of many-electron atoms and molecules.
- Explain the theory underlying the most frequently employed methods used in computational chemistry.
- Derive and use fundamental equations used in the description of the electronic structure of many-electron atoms and molecules.
- Understand the theoretical description of the electronic structure of many-electron atoms and molecules.
