This course discusses the origins of atomic spectra and shows the application of quantum mechanics in describing the interaction between electron and nuclei in atoms.
* Hydrogen atom - central potential approximation, radial wavefunction, quantum numbers, energy levels and degeneracy; electron spin and total angular momentum; spin-orbit coupling and fine structure; Zeeman splitting
* Helium atom - Coulomb repulsion and exchange; singlet-triplet splitting
* Electronic configuration and periodic table; alkali metals; residual electrostatic interaction; LS-coupling scheme; Hund's rules; hyperfine structure and isotope shift
* Selection rules for electric dipole interaction
* Zeeman and Stark effects
* Inner shell transitions and x-ray spectra
* Doppler broadening in laser spectroscopy.
