In a strong electric field the molecular ions of n ‐alkenes ≤C‐12 decompose via cleavage of the CC bond β to the double bond to form the characteristic alkenyl ions that may be used for the identification of positional isomers. For 3‐alkenes (>C‐10), 4‐, 5‐ and 6‐alkenes the formation of the ions with m / e 54 via double β‐cleavage is typical. The field ionization mass spectra of the cis and trans isomers are indistinguishable.
