The loss of a hydrogen atom from ionized 2‐methylpropanenitrile is preceded by a drastic rearrangement of the molecular ion. The result of this fragmentation is the generation of two stable structurally different [C 4 H 6 N] + ions, formed via different pathways. Their structures can be established by a careful comparison of the metastable ion spectra, collision activation spectra, and charge stripping spectra from the compound and its three deuterium labeled analogues and from [C 4 H 6 N] + ions generated from reference compounds via electron impact ionization or in selected ion/molecule reactions.
