Theoretical Underpinnings

At the heart of relativistic electronic structure theory lies the recognition that the motion of electrons, particularly in heavy atoms, cannot be accurately described without considering the effects of special and general relativity. These effects introduce subtle yet profound modifications to the Schrödinger equation, necessitating the development of specialized theoretical frameworks. The Dirac equation, a cornerstone of relativistic quantum mechanics, provides a relativistic description of electron behavior, capturing both its wave-particle duality and spin.
