fragmentation

  1. The heterolytic cleavage of a molecule according to the general reaction:
    F02506-1
    where a-b is an electrofuge and X is a nucleofuge (which may emerge from the reaction in combined form), and the middle group affords the unsaturated fragment c=d. For example,
    F02506-2
  2. The breakdown of a radical into a diamagnetic molecule or ion and a smaller radical, e.g.
    F02506-3
    F02506-4
  3. The breakdown of a radical ion in a mass spectrometer or in solution, forming an ion of lower molar mass and a radical, e.g.
    F02506-5
