The unimolecular dissociation reaction of the methyl vinyl ether radical cation to acetyl cation plus methyl radical was studied by means of 13 C labelling and tandem mass spectrometric techniques. The results are in good agreement, in all major aspects, with previous data for 13 C‐labeled propene oxide. The data are discussed in terms of non‐ergodic behaviour. Isomerization of the methoxyethylidene radical cation intermediate to the acetone radical cation is ruled out on the basis of the labelling experiments and comparison with the hydroxymethene radical cation system.
