The study subject "Introduction to Molecular Physical Chemistry and Symmetry" is focused on basic principles and ideas of molecular quantum mechanics. The understanding of its basic concepts, thoughts, intellections and perceptions is strongly accented in comparison to detailed mathematical description. The principal attention is devoted to the mutual relations between the stationary states and particle localization, the wave packet and particle movement, the tunnel phenomenon and uniqueness . The attention is also devoted to the uncertainty concept, spin of particles, angular momentum in the quantum mechanics as well as to the basic quantum mechanical systems. The part of this course is dedicated to the molecular symmetry groups (point as well as permutation - inversion groups), their representations and applications. Selected quantum chemistry methods are introduced as well as fundaments of vibrational and rotational spectroscopy. Finally, some lectures are devoted to weak molecular interactions, to molecular partition functions and is formulated a relationship between the classical thermodynamics and the molecular quantum mechanics.

Students obtain a basic knowledge of molecular quantum mechanics (QM) and molecular symmetry groups, especially; they should understand the basic difference between the QM and classical mechanics and the difference between their diverse insights to description of the nature. The diverse views are discussed above all in context with the concepts as stationary states, localization and delocalization particles (mass), wavefunctions, eigenvalues, wave packet, Pauli principle, the Franck-Condon phenomenon, space degeneracy, partition functions, weak and hyperfine interaction etc. Last update: VED402 (25.09.2013)
