Relativistic effects are treated in two steps, both based on the Douglas–Kroll Hamiltonian. 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 of this theory. Since relativistic quantum chemistry is an integral component of computational chemistry, this handbook also supplements the “Handbook of Computational Chemistry”. Generally speaking, it aims to establish the ‘big picture’ of relativistic molecular quantum mechanics as the union of quantum electrodynamics and relativistic quantum chemistry.

CAS Article Google Scholar Relativistic quantum mechanics (RQM) is quantum mechanics applied with special relativity. Although the earlier formulations, like the Schrödinger picture and Heisenberg picture were originally formulated in a non-relativistic background, a few of them (e.g. the Dirac or path-integral formalism) also work with special relativity.

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 of Since relativistic quantum chemistry is an integral component of computational chemistry, this handbook also supplements the “Handbook of Computational Chemistry”. Generally speaking, it aims to establish the ‘big picture’ of relativistic molecular quantum mechanics as the union of quantum electrodynamics and relativistic quantum chemistry. Relativistic quantum chemistry has evolved into a fertile and large field and is now becoming an integrated part of mainstream chemistry. Yet, given the much-involved physics and mathematics (as compared with nonrelativistic quantum chemistry), it is still necessary to clean up the essentials underl … Relativistic quantum chemistry is similar to these topics: Relativistic quantum mechanics, Timeline of quantum mechanics, Periodic table and more.
