The students are introduced to advanced concepts and methods of theoretical chemistry and finally to computer modeling and simulations, including links with various computer algorithms. A key aspect of the course is to allow students to understand the role of the input parameters necessary for the calculations. Some specific issues that are treated in the course are the determination of molecular and bulk properties, of molecular reactivities, as well as aspects of electron correlation.

For the quantum chemistry part,
1°) 50% for the written report (length: 3 pages/student). The reports will be submitted by November 30th at the latest. The report should include the presentation and critical discussion of the results.
2°) 50% for the written exam (1H of preparation) on the essential aspects of DFT and TDDFT, followed by a oral discussion (Questions will be asked on the methodological DFT and TDDFT aspects as well as on the results of the project).
