Methyl vinyl ketone oxide is an important Criegee intermediate formed during the ozonolysis of isoprene, but its formation and resonance stabilization remain poorly characterized. Here, transient infrared spectroscopy of the syn-trans-conformer shows a stronger O‒O stretching band at 948 cm-1 that confirms the stabilization.
