This has to do with two facts: a) Often the spatial regions close to the nuclei are involved, b) Often electronic spin is a basic variable. Nowadays relativistic approaches are routinely implemented and applied in standard quantum chemical software packages.

As it is essential for chemists and physicists to understand relativistic effects in molecules, the first edition of ‘Relativistic Quantum Chemistry – The fundamental Theory of Molecular Science’ had set out to provide a concise, comprehensive, and complete presentation Quantum chemistry, also called molecular quantum mechanics, is a branch of chemistry focused on the application of quantum mechanics to chemical systems. Understanding electronic structure and molecular dynamics using the Schrödinger equations are central topics in quantum chemistry. The basic ideas of relativistic quantum chemistry are highlighted, with the most important ingredients summarised as follows. (1) The restricted kinetic balance Feb 20, 2012 Non-relativistic quantum chemistry willingly ignores relativistic effects, such as retardation, magnetic interaction between the electrons, Mar 23, 2012 Relativistic quantum chemistry on quantum computers. Libor Veis, Jakub Višňák, Timo Fleig, Stefan Knecht, Trond Saue, Lucas Visscher, and Given the remarkable advances in relativistic quantum chemistry, some conceptual aspects still remain to be addressed.

Its five sections cover classically relativity background; the Dirac question; four component methods, including symmetry, correlation, and properties; approximate methods, including perturbation theory, transformed Hamiltonians, regular approximations, matrix approximations, and pseudopotential methods The two basic theories of modem physics are the theory of relativity and quantum mechanics. While the importance of the latter in chemistry was instantly recognized, it was not until the 19708 that the full relevance of relativistic effects in heavy-element chem- istry was discovered.
