Relativistic effects are more prominent in heavy elements because only in these elements do electrons attain relativistic speeds. Quantum chemistry uses the RQM to explain elemental properties and structure, especially for the heavy metals of the periodic table.

M. Kaupp, in Theoretical and Computational Chemistry, 2004 1 Introduction. Few physico-chemical properties of atoms, molecules or solids are as intrinsically connected to relativistic quantum mechanics as the parameters of magnetic resonance spectroscopy. 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.

= (4rc0)(h2/me2) (W will decrease for inner electrons with large average speeds. For a 1s shell at the nonrelativistic limit, this average speed is 2 au. Thus the 1s Relativistic quantum chemistry invokes quantum chemical and relativistic mechanical arguments to explain elemental properties and structure, especially for the heavier elements of the periodic table. A prominent example of such an explanation is the color of gold; due to relativistic effects, it is not silvery like most other metals. A multiconfigurational approach to the quantum chemistry of heavy element compounds is described. Relativistic effects are treated in two steps, both based on the Douglas–Kroll Hamiltonian.

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. Among others, the role of negative This book provides an introduction to the essentials of relativistic effects in quantum chemistry, and a reference work that collects all the major developments in Nov 15, 2011 Finally, we propose quantum circuits with 3 qubits and 9 or 10 CNOTs, which implement a proof-of-principle relativistic quantum chemical In physics, relativistic quantum mechanics (RQM) is any Poincaré covariant formulation of quantum mechanics (QM).

Specifically, we focus on two groups of methods. Quantum chemistry is just quantum mechanics applied to chemistry problems. And well, in many cases we can treat our systems ignoring relativistic effects and still get reasonable results, but especially for heavy atoms those effects get quite huge so we need to count them in.
