- Course Enrolment Limitations
- The course is offered to students of any study field.
- Course objectives
- The aim of the course is to provide students with an introduction to the spectroscopy of atoms and diatomic molecules, especially in the UV / VIS spectral region (electronic transitions), to a lesser extent also in the IR spectral region (vibrational and rotational molecular transitions). Within the subject, the simplest systems (atom of hydrogen, helium, alkali metal, rotating molecule, vibrating molecule, ...) are analyzed using quantum mechanics. The aim is to give an idea of the interactions that take place inside the atom or molecule, quantify their effect on the resulting energy and show how these effects are reflected in the observed transitions, in the used quantum state labelling etc. Quantum mechanics is used in it's simplest form. The aim of the lesson is also to realize which of the phenomena explained are measurable or usable in plasma diagnosis with the current spectroscopy equipment at the institute.
- Learning outcomes
- At the end of the course the students will understand basics of atomic and molecular physics making possible to use them for diagnostics of plasmas by means of optical spectroscopy. Students obtain practical experiences at laboratory measurements of typical spectra as well as at solutions of typical problems from atomic and molecular spectroscopy.
