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. |
