Quantum Chemistry Fundamentals: Atomic Structure and Spectroscopy

Quantum chemistry is the bedrock of modern physical science, explaining why matter behaves the way it does at the subatomic level. This course provides a thorough, text-based introduction to the quantum mechanical description of atoms. You will move past classical models to master concepts like wave functions, orbitals, and quantum numbers, preparing you for advanced studies in molecular chemistry, materials science, and spectroscopy. What you'll learn: * Understand the historical development and foundational postulates of quantum mechanics. * Master the solutions to the Schrödinger equation for simple systems, including the hydrogen atom. * Apply quantum numbers and selection rules to describe atomic orbitals and electron configurations. * Analyze atomic spectra and interpret how quantum transitions lead to observable properties. * Practice interpreting basic computational chemistry results, including energy calculations and basis set concepts. The material begins with the mathematical foundations and early experiments that necessitated quantum theory. We then systematically explore the quantum description of the atom, focusing on orbital shapes, electronic states, and how these principles extend to multi-electron systems. This course is designed for absolute beginners in physical chemistry, students needing a strong foundation for university-level quantum courses, or professionals seeking to understand the quantum basis of chemical phenomena. No prior knowledge of quantum mechanics or advanced mathematics is required. Start building your foundational knowledge of quantum chemistry today.
