Details | The Hartree (Ha) is a unit of energy commonly used in quantum chemistry and atomic physics, particularly in the field of computational chemistry and electronic structure calculations. It is named after the British physicist Douglas Hartree, who was a pioneer in this field. In Hartree atomic units, one Hartree is the natural unit of energy equal to approximately 27.211386245 electron volts (eV) or 4.35974 × 10^(-18) joules (J). It represents the energy required to: (1) ionize an electron in a hydrogen atom from the ground state (the lowest energy level) or (2) create an electron-hole pair in a hydrogen atom. The unit thus simplifies atomic-scale calculations and provides a convenient way to express and compare energies for various atomic and molecular phenomena. |
