The Hartree is a unit of energy commonly used in atomic and molecular physics, particularly in quantum chemistry. It is defined as approximately \\(4.36 \\times 10^\{-18\}\\) joules or \\(27.2\\) electron volts (eV). The Hartree energy is equivalent to the energy of an electron in the electrostatic field of a proton, and thus it provides a convenient scale for measuring energy levels and interactions in atoms and molecules.
