_Introduction to Quantum Mechanics, 2nd Edition_ provides an accessible, fully updated introduction to the principles of quantum mechanics. It outlines the fundamental concepts of quantum theory, discusses how these arose from classic experiments in chemistry and physics, and presents the quantum-mechanical foundations of current scientific developments.Beginning with a solid introduction to the key principles underpinning quantum mechanics in Part 1, the book goes on to expand upon these in Part 2, where fundamental concepts such as molecular structure and chemical bonding are discussed. Finally, Part 3 discusses applications of this quantum theory across some newly developing applications, including chapters on Density Functional Theory, Statistical Thermodynamics and Quantum Computing.Drawing on the extensive experience of its expert author, _Introduction to Quantum Mechanics, 2nd Edition_ is a lucid introduction to the principles of quantum mechanics for anyone new to the field, and a useful refresher on fundamental knowledge and latest developments for those varying degrees of background. * Presents a fully updated accounting that reflects the most recent developments in Quantum Theory and its applications * Includes new chapters on Special Functions, Density Functional Theory, Statistical Thermodynamics and Quantum Computers * Presents additional problems and exercises to further support learning
