  "term": "Wahrhaftig diagram",
  "field": "Chemistry",
  "definition": "A two-part diagram for unimolecular ion dissociation that shares a horizontal axis of internal energy. One part plots the logarithm of the rate constants of competing dissociation pathways, such as direct bond cleavage and fragmentation after rearrangement, against internal energy, and the other part shows the distribution function of internal energies of the ions. Where the rate curves cross, the favoured pathway changes.",
