Infrared Spectrum of the Adduct 2-Chloro-2-hydroperoxybut-3-ene [(C₂H₃)CCl(CH₃)OOH] of the Reaction between the Criegee Intermediate Methyl Vinyl Ketone Oxide [C₂H₃C(CH₃)OO] and HCl.

ABSTRACT: Methyl vinyl ketone oxide (MVKO, C₂H₃C(CH₃)OO) is an important Criegee intermediate produced from ozonolysis of isoprene, which is the most abundant nonmethane hydrocarbon emitted into the atmosphere. Reactions between Criegee intermediate and hydrogen chloride (HCl) are important because of their large rate coefficients. In this work, we photolyzed a mixture of (Z)-(CH₂I)HC═C(CH₃)I/HCl/O₂ at 248 nm to produce MVKO to carry out the reaction MVKO + HCl and recorded infrared spectra of transient species with a step-scan Fourier-transform infrared absorption spectrometer. Eleven bands near 1415, 1381, 1350, 1249, 1178, 1118, 1103, 1065, 978, 931, and 895 cm^-1 were observed and assigned to the hydrogen-transfer
