Hartree Energy
The Hartree energy is a unit of energy that is commonly used in quantum chemistry and atomic physics. It is named after the British physicist Douglas Hartree, who made significant contributions to computational methods in physics and chemistry. The Hartree energy is defined in terms of the Rydberg constant and is equivalent to approximately 4.35974 × 10-18 joules or 27.2114 eV (electronvolts).
This unit represents the energy associated with the interaction of an electron with a nucleus in a hydrogen atom, providing a convenient scale for atomic and molecular systems. The Hartree energy is particularly useful when working with quantum mechanical calculations, such as in the field of Density Functional Theory and other computational chemistry methods. Its significance lies in its ability to simplify the representation of energy levels and transitions in atoms and molecules.
