The infrared quasi‐resonance stepwise‐multiphoton‐dissociation spectra of the molecular ions of 1‐bromo‐propene, 2‐bromopropene, 3‐bromopropene, and bromocyclopropane have been obtained at selected wavelengths between 9. 2 and 10. 7 μm in a Fourier ‐transform mass spectrometer. The resulting spectra and the photo fragmentation kinetics suggest that these molecular ions retain their identity upon ionization, and can, thus, provide fingerprint spectral identifications for the ions.
