Molecular Quantum Mechanics is a well-established academic textbook on quantum mechanics and its applications to the structure and behaviour of atoms and molecules. It introduces the fundamental principles of quantum theory as a framework for understanding microscopic matter and explains how these principles can be used to investigate atomic and molecular structures, energy levels, and quantum interactions. The book begins with the foundations of quantum mechanics and covers topics such as linear motion, the harmonic oscillator, rotational motion, the hydrogen atom, angular momentum, group theory, and approximation methods. It then explores atomic and molecular structure, computational chemistry, molecular rotations and vibrations, electronic transitions, and the electric and magnetic properties of molecules. The final part introduces scattering theory. A major strength of the book is its systematic integration of mathematical foundations with physical and chemical applications. Worked examples, mathematical explanations, and illustrative figures help readers move beyond a conceptual understanding toward applying quantum-mechanical methods to atomic and molecular systems. It is particularly suitable for students and researchers seeking a deeper theoretical understanding of quantum chemistry and the electronic structure of matter.
