A tandem Dempster‐ion cyclotron resonance mass spectrometer was used to examine metastable transitions in benzene, toluene, anisole and anisole 1,3,5‐ d 3 . The tandem‐ion cyclotron resonance technique examines all unimolecular reactions of the injected, mass‐selected ion, which occur between the injection time of several microseconds and the ion cyclotron resonance reaction section residence time of several milliseconds. The long sampling interval results in different relative intensities and considerably larger isotope effects than have been observed in previous studies.
