Fragmentation is a type of Dissociation chemistry chemical dissociation . Fragmentation of a molecule can take place by a process of heterolysis or homolysis . It is a phenomenon observed in mass spectrometry where it is used as a tool to find the structural formula of a molecule, process called structural elucidation . It can occur in the ion source in source fragmentation where it is generally not a desired effect. Ion source conformation is an important criterium in the level of fragmentation observed. Desired fragmentation is made in the collision zone post source fragmentation of a tandem mass spectrometry tandem mass spectrometer . It is a part of gas phase ion chemistry and there are different types of mass fragmentation collision induced dissociation CID , electron capture dissociation ECD , electron transfer dissociation ETD , negative electron transfer dissociation NETD , electron detachment dissociation EDD , photodissociation , particularly infrared multiphoton dissociation IRMPD and blackbody infrared radiative dissociation BIRD , surface induced dissociation SID , Higher energy C trap dissociation HCD , charge remote fragmentation .

When the word grenade is used without specification, and context does not suggest otherwise, it is generally assumed to refer to a fragmentation grenade.
