[C 13 H 9 S] + , [C 14 H 11 ] + , [C 13 H 11 ] + and [C 8 H 7 S] + ions with unknown structures were generated from two [C 14 H 12 S] +· precursor ions by fragmentation reactions that must be preceded by extensive rearrangements. Ions with the same compositions, each with several initial structures, were prepared by simple bond‐breaking reactions. Metastable characteristics were compared for each of the four types of ions. It was found than in all cases fast isomerization reactions occur prior to fragmentation, so that no information about the unknown ion structures could be obtained by comparison of the observed fragmentations of metastable ions.
