Molecular Symmetry

In the first part of this course the necessary mathematical background of molecular symmetry, i.e., group theory, is introduced. The second part deals with the applications of group theory in chemical bonding, vibrational spectra and chemical reactions.
The course is taught in English for ERASMUS students in a consultation form.

Exam consists in written and oral parts. The written part includes three problems: the first one concerns electronic structure of molecules, the second one is related to vibrations of molecules and the third one is related to chemical reactivity. The oral part concerns the fundamentals topics of the course. If necessary, the couse and the exam will have a distant form.
