With the aid of the mass spectra of 14,14‐d 2 analogues the majority of the m/e 98 ions in the spectrum of allomatridine were shown to contain ring D, whereas in the case of matridine and isosophoridan the m/e 98 ions mainly include rings A or B. The m/e 84 ion results mostly from a charge localisation on ring D for allomatridine and isosophoridan, while in the case of matridine it may arise due to charge localisation on ring D accompanied by migration of the 14‐H atom from the charged fragment, as well as on rings A or B with a hydrogen atom migrating to the charged species.
