A molecule on a slippery slope : Lineberger et al. finally managed to observe the oxyallyl diradical 1 using negative ion photoelectron spectroscopy. The singlet state of the oxyallyl diradical is lower in energy than the triplet and corresponds to the transition state for ring closure to cyclopropanone 2 .
