Atomic and Molecular Physics, 7.5 credits

About this education

One- and multi-electron atoms are studied quantum mechanically, where the effects due to spin, the fine-structure, and the hyperfine structure are also taken into consideration. Time-dependent perturbation theory is discussed in detail, and used to describe both the fine-structure and Zeeman effects in atoms. The physical basis for the binding in diatomic molecules and simple polyatomic molecules is discussed. The fundamental approximations which underpin the theoretical descriptions of molecules are studied. The variational principle

is used to calculate atomic and molecular wave functions. The interaction of atoms and molecules with electromagnetic radiation is studied and the selection rules governing these interactions discussed.
