Fundamentals of Atomic and Molecular Physics

Atomic and Molecular Physics explains how matter interacts with energy, offering the fundamental principles necessary for fields like quantum optics, materials science, and physical chemistry. Upon completion, you will possess a solid conceptual and mathematical understanding of atomic structure, selection rules, and the analysis of molecular spectra (rotational, vibrational, and electronic). What you'll learn: * Understand the quantum mechanical description of single and multi-electron atomic systems using appropriate notation. * Apply selection rules to analyze spectroscopic data and interpret fine and hyperfine structures. * Master the principles behind the Zeeman and Stark effects when atoms are placed in external magnetic and electric fields. * Learn the fundamental operational principles behind modern laser systems and their applications in high-resolution spectroscopy. * Practice applying quantum principles to calculate energy levels and transitions in diatomic molecules. * Configure the basic models used to describe molecular bonding, rotation, and vibration. The course begins with foundational concepts of quantum numbers and basic atomic models, progressing systematically through atomic spectra, molecular bonding, and advanced spectroscopic techniques. Written explanations clarify complex theory alongside practical examples and exercises. This course is designed for absolute beginners in physics or chemistry who need a foundational understanding of matter at the quantum level. No prior advanced knowledge of quantum mechanics is required. Start mastering the building blocks of the universe today.
