Publisher's Summary:
Written by two researchers in the field, this book is a reference to explain the principles and fundamentals in a self contained, complete and consistent way. Much attention is paid to the didactical value, with the chapters interconnected and based on each other. The contents include: Fundamentals; Relativistic Theory of a Free Electron: Dirac's Equation; Dirac Theory of a Single Electron in a Central Potential; Many Electron Theory I: Quantum Electrodynamics; Many Electron Theory II: Dirac Hartree Fock Theory; Elimination of the Small Component; Unitary Transformation Schemes; Relativistic Density Functional Theory; Physical Observables and Molecular Properties; and Interpretive Approach to Relativistic Quantum Chemistry. From beginning to end, the authors deduce all the concepts and rules, such that readers are able to understand the fundamentals and principles behind the theory. It is essential reading for theoretical chemists and physicists.
