  "id": "MLC-T-CHM-004257",
  "term": "Extended Hückel MO method",
  "field": "Chemistry",
  "definition": "A semi-empirical quantum mechanical method used to calculate molecular orbital energies and wavefunctions for molecules. It is an extension of the simpler Hückel method, incorporating all valence electrons and considering overlap integrals between atomic orbitals. This method provides a qualitative understanding of electronic structure and bonding in organic and inorganic compounds.",
