Introduction to Quantum Chemistry e-bog

Quantum Chemistry is a branch of theoretical chemistry, which applies quantum mechanics and quantum field theory to address issues and problems in chemistry. The description of the electronic behaviour of atoms and molecules as pertaining to their reactivity in one of the applications of quantum chemistry. Quantum chemistry lies on the border between chemistry and physics, and significant contributions have been made by scientists from both fields. It has a strong and active overlap with the field of atomic physics and molecular physics, as well as physical chemistry. Modern research in quantum chemistry is focused on improving its multi faceted utility calculating molecular properties. The book is designed to provide an integrated approach to the conceptual development of quantum chemistry and to its application in current research question. It is intended to be modest and straightforward, easily completed in its entirety either in one-semester formal course. This modern introduction to quantum chemistry covers quantum mechanics, atomic structure, and molecular electronics, and clearly demonstrates the usefulness and limitations of current quantum-mechanical methods for the calculation of molecular properties.
