The aim of this course is to provide students with an understanding of the fundamental concepts, theoretical foundations, and quantum mechanical descriptions of atomic and molecular physics. The course examines atomic structure, atomic spectra, multi-electron atoms, and the physical properties of molecular systems, aiming to develop students’ abilities to analyze, interpret, and solve problems in atomic and molecular physics.

This course covers the fundamental concepts of atomic physics, including the Bohr and Sommerfeld atomic models, quantum mechanics of the hydrogen atom, atomic orbitals, electron spin, and angular momentum. Topics such as multi-electron atoms, atomic spectra, the Zeeman, Paschen-Back, and Stark effects, X-rays, and the Hartree-Fock method are also discussed. In the molecular physics section, the quantum mechanical description of molecules, the application of the Schrödinger equation to molecular systems, and the structure and energy levels of diatomic molecules are examined.
