Centrifugal barrier

  "id": "MLC-T-CHM-001796",
  "term": "Centrifugal barrier",
  "field": "Chemistry",
  "definition": "A potential energy barrier arising from the angular momentum of colliding particles in a chemical reaction. This barrier impedes the approach of reactants, particularly at low collision energies, by effectively increasing the repulsive forces between them. It is a component of the overall potential energy surface that must be overcome for a reaction to proceed.",
