Foundations of Atomic and Molecular Physics

Atomic and molecular physics forms the bedrock of modern quantum science and chemistry. Understanding these foundational principles is essential for advanced study and research in physical sciences. This course provides a rigorous, text-based introduction to the structure, spectra, and interactions governing atoms and molecules, preparing you to tackle complex theoretical problems with confidence. What you'll learn: * Understand the quantum mechanical treatment of single-electron and multi-electron atoms, including spin-orbit coupling and LS and jj coupling schemes. * Learn to interpret atomic spectra using selection rules, term symbols, and the effects of external fields like the Zeeman effect. * Master the fundamental principles of molecular bonding, including the Born-Oppenheimer approximation and potential energy curves. * Apply the principles of rotational, vibrational, and electronic spectroscopy (including Raman) to analyze molecular structure and dynamics. * Practice solving problems related to quantum numbers, parity, and interpreting characteristic spectral features. We begin with the quantum origins of atomic structure, progress through spectroscopic notation and selection rules, and conclude by applying these concepts to the analysis of simple molecules and their characteristic spectra. This course is designed for absolute beginners in advanced physics or chemistry who need a strong theoretical foundation in atomic and molecular principles. No prior knowledge of quantum physics is assumed. Start building your expertise in quantum systems today.
