Indirect reaction

  "id": "MLC-T-CHM-005782",
  "term": "Indirect reaction",
  "field": "Chemistry",
  "definition": "A reaction in which the colliding reactants form a reactive complex that lives longer than its period of rotation before breaking into products, also called a complex-mode reaction. Because the complex loses memory of the approach direction, the products in a molecular-beam experiment scatter at random with respect to the center of mass. It contrasts with a direct reaction, whose complex lives for less than one rotation and gives products scattered in preferred directions.",
