Atomic and Molecular Physics with Solved Practice Problems

Navigating the complexities of atomic and molecular physics requires a strong grasp of both theoretical principles and mathematical problem-solving. This text-based course is designed to bridge the gap between abstract quantum mechanics and the practical application needed for competitive physics examinations. You will develop a deep intuitive understanding of physical phenomena and build the analytical skills necessary to solve challenging academic problems. By working through clear, structured explanations, you will learn to dissect complex physical systems and confidently approach standard exam questions. What you'll learn: - Understand the foundational quantum mechanics of hydrogen-like atoms and alkali spectra - Analyze fine structure, hyperfine structure, and the Zeeman and Paschen-Back effects - Master rotational, vibrational, and electronic molecular spectroscopy principles - Apply selection rules to predict transition states and spectral lines - Practice step-by-step derivations and problem-solving methodologies for key exam-style questions - Explore modern concepts in laser physics and basic atomic cooling techniques This course begins with core definitions and essential mathematical formalisms before moving into detailed physical models and spectroscopy. You will progress from single-electron systems to complex multi-electron molecules, supported by comprehensive written walkthroughs of classic exam problems. This course is designed for physics students, educators, and candidates preparing for competitive graduate-level physics assessments. No advanced prerequisites are required, though a basic familiarity with introductory quantum mechanics and calculus is highly recommended.
