Abstract

Breaking down a Criegee intermediate Ozone's damaging role in the upper atmosphere is well known, but ozone is also quite active closer down to where we live. In particular, ozone's run-ins with airborne unsaturated hydrocarbons, from natural or anthropogenic sources, produce even more-reactive OH radicals. Liu et al. used vibrational spectroscopy to study how OH emerges from a so-called Criegee intermediate formed when ozone attacks 2-butene. The results suggest that OH production is easier than current theory predicts. Science , this issue p. 1596
