Spin-flip method

  "id": "MLC-T-CHM-011211",
  "term": "Spin-flip method",
  "field": "Chemistry",
  "definition": "A quantum chemical approach used to describe electronic states that differ by a single spin flip, particularly useful for systems with diradical character or multiple electronic states. This method starts from a high-spin reference state and then flips the spin of one electron to access lower-spin states. It is effective for calculating excitation energies and potential energy surfaces.",
