Alkene ozonolysis generates short-lived Criegee intermediates that are a significant source
of hydroxyl (OH) radicals. This study demonstrates that roaming of the separating OH …

A prototypical hydroperoxyalkyl radical (• QOOH) intermediate, transiently formed in the
oxidation of volatile organic compounds, was directly observed through its infrared …

Key combustion properties, such as ignition delay time, show strong sensitivity to the
thermochemistry of the main species in the standard radical oxidation pathway at low …

Methyl-ethyl-substituted Criegee intermediate (MECI) is a four-carbon carbonyl oxide that is
formed in the ozonolysis of some asymmetric alkenes. MECI is structurally similar to the …

Carbonyl oxides, R1R2COO, alternatively known as Criegee intermediates (CIs), are short-
lived molecules produced from ozonolysis of alkenes. These ozonolysis reactions yield …

One hundred years ago, at an earlier Faraday Discussion meeting, Lindemann presented a
mechanism that provides the foundation for contemplating the pressure dependence of …

Alkene ozonolysis generates transient carbonyl oxide species, known as Criegee
intermediates, which are a significant nonphotolytic source of OH radicals in the …

A novel allylic 1, 6 hydrogen-atom-transfer mechanism is established through infrared
activation of the 2-butenal oxide Criegee intermediate, resulting in very rapid unimolecular …

Atmospheric ozonolysis of biogenic and anthropogenic alkenes generates zwitterionic
carbonyl oxide intermediates (R1R2C═ O+ O–), known as Criegee intermediates, with …

Unimolecular decay of the formaldehyde oxide (CH2OO) Criegee intermediate proceeds via
a 1, 3 ring-closure pathway to dioxirane and subsequent rearrangement and/or dissociation …
