US and UK researchers report direct measurement of key atmospheric reactant; more rapid formation of secondary aerosols
Green Car Congress

Molecules called Criegee intermediates—carbonyl oxides—are important atmospheric reactants, but only indirect knowledge of their reaction kinetics has been available. However, until 2008 no gas-phase Criegee intermediate had been observed, and rate coefficients derived from indirect measurements spanned orders of magnitude.
