Overview

A Primer on Quantum Chemistry A practical and accessible guide to the applications of quantum chemistry Quantum chemistry, the branch of physical chemistry which applies quantum mechanical principles to the study of chemical systems, has become an integral part of the study of matter. Concerned with understanding quantum effects at the atomic and molecular level, quantum chemistry underlies an immense range of modern technologies. A Primer on Quantum Chemistry provides a lucid introduction to the difficult mathematical and conceptual foundations of this essential field. It incorporates Mathematica for operations in algebra and calculus, enabling readers to focus on the physical and chemical principles. It thereby equips students with the tools used by professional scientists in applications of quantum chemistry. A Primer on Quantum Chemistry readers will also find: Detailed treatment of subjects including the Schrödinger equation and many more Supplemental online material including problems, solutions, and details of Mathematica computations A carefully developed pedagogical approach that streamlines student progress through the subject A Primer on Quantum Chemistry is a must-own for graduate and advanced undergraduate students in chemistry, physics, and related subjects.
