Evidence has been reported that primary loss of H and of HCN from the molecular ions of propionitrile, isobutyronitrile and butyronitrile in the mass spectrometer is preferentially preceded by hydrogen migration from C‐2 to C‐1. Ion cyclotron double resonance spectra of proton (or deuteron‐) transfer products derived from propionitrile‐2‐d2 and ‐3‐d3 and a series of bases provide evidence that such migration occurs also in long‐lived propionitrile molecular ions.
