An electrically charged product of reaction of a particular parent ion. In general
such ions have a direct relationship to a particular precursor ion and indeed may
relate to a unique state of the precursor ion. The reaction need not necessarily involve
fragmentation. It could, for example, involve a change in the number of charges carried. Thus,
all fragment ions are daughter ions, but not all daughter ions are necessarily fragment
ions.
