Production of the radicals in the ozonolysis of ethene: A chamber study by FT-IR and PERCA

The ozonolysis of ethene was investigated in a reaction chamber by in situ analysis of stable species by FTIR and of total peroxy radicals PO2 (PO2 = HO2 + RO2) by a chemical amplifier instrument. The yields of radical production were determined based on steady state concentrations of the peroxy radicals and the partitioning between HO2 and RO2 derived from model simulations.
