An introduction to quantum mechanics (QM) for students of chemistry. Physical principles of QM and its typical applications. Characteristic features of microscopic systems: the quantization of energy and the other observables, the wave charakter of particles, the uncertainty principle, the importance of the measurement. The selected topics: the description of quantum states, the operator treatment of physical observables, Schrödinger equation, the elementary introduction to QM of many-partical systems, the QM-clarification of the chemical bond. The relation of QM to classical mechanics.
