Computer modeling of chemical and biochemical processes, such as organic and bioinorganic reactions, including enzymatic reactions, is an integral part of our understanding of these processes at atomic or even electron level. The aim of this course is to get acquainted with modern methods of theoretical and computational chemistry. Emphasis is placed on combined methods of quantum mechanics and molecular mechanics (QM / MM), practical use of statistical mechanics including the theory of transition state and its relation to chemical reactivity and selectivity, explanation of the principles of modern solvation methods, use of molecular dynamics for statistical sampling of phase space, comparison of calculated data with experimental data and critical evaluation of the suitability of individual methods for solving practical problems. Last but not least, the course also deals with the redox processes in bioanorganic systems and the methods of their theoretical description. Lectures are held - after an agreement - in English.

Requirements to the exam -
Last update: prof. Mgr. Lubomír Rulíšek, DSc. (26.06.2019)

The exam takes the form of homework assignments at the end of the course and a short oral interview. A student is required to have a deeper understanding of the subject, that is to understand basic principles of enzyme catalysis and chemical reactivity, without the need for detailed knowledge of all equations and their derivation.
