Relativistic Molecular Theory
Takahito Nakajima
Relativistic molecular theory, REL4D
This brief review contains surveys of both four-component and two-component relativistic molecular theories. First the four-component relativistic approach is reviewed. Emphasis is placed on efficient computational schemes for the four-component Dirac-Hartree-Fock and Dirac-Kohn-Sham methods. Next, in the twocomponent relativistic framework, two relativistic Hamiltonians, RESC and higher-order Douglas-Kroll (DK), are introduced. An illustrative application is shown for the relativistic study on valence photoelectron spectrum of OsO4. The developing four-component relativistic and approximate quasi-relativistic methods have been packed in a program suite named REL4D.
