  "term": "Configuration interaction",
  "field": "Chemistry",
  "definition": "A post-Hartree-Fock method in quantum chemistry that accounts for electron correlation by expressing the true electronic wavefunction as a linear combination of Slater determinants. These determinants are constructed from molecular orbitals obtained from a Hartree-Fock calculation. The coefficients in the linear combination are determined by minimizing the energy, leading to a more accurate description of molecular properties than the single-determinant Hartree-Fock approximation.",
