Fig. 2: Absorption spectra measured during ozonolysis of ethene with the presence (in blue) and absence (in black) of high-concentration SO2 (used as a scavenger).

From: Direct measurement of the Criegee intermediate CH2OO in ozonolysis of ethene

Fig. 2

The CH2OO concentration decreased by more than 95% after the addition of the scavenger (see enlarged Supplementary Fig. 3). The SO2 reference spectra (Vandaele et al.77, in orange) were obtained from the MPI-Mainz UV/VIS Spectral Atlas62. The CH2OO reference (in red) was scaled from cross-section data of Foreman et al.34 Source data are provided as a Source Data file.
