Notably, the Relativistic effects in chemistry can be considered to be perturbations, or small corrections, to the non-relativistic theory of chemistry, which is developed from the May 14, 2020 Relativistic quantum chemistry has evolved into a fertile and large field and is now becoming an integrated part of mainstream chemistry. This Award Account focuses on the author's studies on the theoretical developments of two-component (2c) relativistic quantum chemistry calculations for large Relativistic Quantum Chemistry (RQC) has become a large and fertile field.

However, unlike the Schrödinger–Coulomb (SC) Hamiltonian that has well-defined mathematical and spectral properties, such ad hoc relativistic Hamiltonians have serious problems. 16,21 16. relativistic quantum chemistry the relativistic mass increase m = mo/(l - (U/C))1'* (la) mo being the rest mass and u the speed of the electron, the effective Bohr radius, a. = (4rc0)(h2/me2) (W will decrease for inner electrons with large average speeds.

## 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. Scalar terms are included in the basis set generation and are used to determine wave functions and energies, which include static (through the use of the CASSCF

## 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.
