  "term": "Primitive change",
  "field": "Chemistry",
  "definition": "A fundamental alteration in the geometry of a reacting system, such as a change in bond length or bond angle, that occurs during a chemical reaction. These changes are the basic components that describe the movement of atoms along a reaction coordinate. They are often analyzed in terms of internal coordinates.",
