1994,,, 203-230. As such, the DC and DCG Hamiltonians have been the major basis of relativistic quantum chemistry for molecular chemistry and physics. 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.
For a long time it was believed that this theory has no significant impact on chemistry. This view changed in the 1970s when it was realized that (nonrelativistic) Schrodinger quantum mechanics yields results on molecular properties that depart significantly from experimental results. * Interpretive Approach to Relativistic Quantum Chemistry From beginning to end, the authors deduce all the concepts and rules, such that readers are able to understand the fundamentals and principles behind the theory.
