ORANGE BOOK DEFINITION

IUPAC. Analytical Division. Compendium of Analytical Nomenclature (the “Orange Book”). Definitive Rules, 1979.

Daughter ion

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

Daughter ion and related terms

QUOTED TEXT FROM IUPAC RECOMMENDATIONS 2013
The anthropomorphic terms for ions involved in fragmentation reactions, for example, “daughter ion”, have fallen into disuse after strong sentiments against the use of the term were voiced two decades ago [1][2]. The term product ion is recommended in place of daughter ion and precursor ion in place of parent ion. The use of nth-generation product ion is recommended in place of granddaughter ion and similar terms.
