WebDefinition of Hartree in the Definitions.net dictionary. Meaning of Hartree. What does Hartree mean? Information and translations of Hartree in the most comprehensive … WebThe Hartree-Fock equations can be solved numerically (exact Hartree-Fock), or they can be solved in the space spanned by a set of basis functions (Hartree-Fock-Roothan equations). In either case, note that the solutions depend on the orbitals. Hence, we need to guess some initial orbitals and then refine our guesses iteratively.
