Criegee intermediates and their impacts on the troposphere

Criegee intermediates (CIs), carbonyl oxides formed in ozonolysis of alkenes, play key roles in the troposphere.

Impact of the water dimer on the atmospheric reactivity of carbonyl oxides

The atmospheric reactivity of carbonyl oxides with water vapor depends on the nature of the carbonyl oxide, on the temperature and on the relative humidity as well.

Carbonyl oxides, or Criegee intermediates, are formed from the gas phase ozonolysis of alkenes and play a pivotal role in night-time and urban area atmospheric chemistry.
