Criegee intermediates have long been seen as an elusive radical, key to the chemistry of the troposphere, but not readily detectable, either in situ or under laboratory conditions. Over the last few years new synthetic methods have been developed to afford detection of some small stabilized Criegee intermediates under controlled laboratory conditions. This, in turn, has allowed the physical and atmospheric chemistry communities to greatly advance our understanding of these species, and how they influence the chemistry of the troposphere. Here we take a chronological course through some spectroscopic, dynamics and kinetics measurements made on these intermediates since 2012, and highlight some of our most recent advances in experimental and computational knowledge of more localised Criegee intermediate chemistry.’
