The mass spectra of the isomeric aminoisoquinolines and 5‐amino‐ 15 N‐isoquinoline are reported. In the aminoisoquinolines, the major fragmentation pathway was the loss of two molecules of HCN and a hydrogen atom to give the m / e 89 fragment ion. Two additional pathways culminating with this ion were observed. The mass spectrum of 5‐amino‐ 15 N‐isoquinoline showed a preference of 4 to 1 for loss of HC 15 N (benzenoid amine group) over HC 14 N (heterocyclic nitrogen) from the molecular ion.
