Module description

A familiarity with the spectrum of hydrogen atoms is expected. A brief recap of relevant aspects of prerequisite courses is followed by the relevant aspects of the underlying quantum mechanics. The spectra of H atoms, alkali metals and alkaline earths and the influence of external magnetic fields (Zeeman effect) provide the data for the study of parameters influencing atomic energy levels and transitions between them. The coupling of orbital and spin angular momenta, the Pauli Exclusion Principal, etc., are discussed and the specification of electronic states is explained. Selection rules and their consequences are presented.
