Module Details

At the end of this course the student should be able to:

  1. Understand the quantum mechanical description of a particle’s translational, rotational and vibrational motions.
  2. Describe the electronic structure of hydrogenic atoms and many-electron atoms, and explain the energy spectrum of hydrogen.
  3. Demonstrate knowledge of basic concepts of the molecular orbital approximation, and the methods that can be used to describe the structures of diatomic and polyatomic molecules.
  4. Understand the origin of atomic and molecular spectra and discuss the selection rules governing such spectra.
  5. Apply molecular spectroscopy in research experiments to determine appropriate experimental methods that are most relevant to a specific problem.

At the end of the course the student will have further developed the following skills/competences:

  1. Ability to carry out mathematical calculations on simple quantum systems and comprehend basic quantum mechanical applications.
  2. Ability to determine the electronic structure of an atom according to the modern quantum theory and to interpret atomic spectra.
  3. Ability to analyze and interpret rotational and vibrational spectra of molecules and obtain information related to their physical properties and structure.
