  "term": "Pariser-Parr-Pople method",
  "field": "Chemistry",
  "definition": "A semi-empirical molecular orbital method used in quantum chemistry to calculate the electronic structure of pi-electron systems, particularly in conjugated organic molecules. It simplifies the full Hamiltonian by neglecting certain electron repulsion integrals and approximating others. This method is primarily applied to planar conjugated systems.",
