Emission from FCO in the Reactions of Ozone with Fluoroethenes

Article abstract of DOI:10.1021/j150626a024

The gas-phase reactions of ozone with cis-1,2-difluoroethene, trans-1,2-difluoroethene, trifluoroethene, and chlorotrifluoroethene are all accompanied by light with a maximum intensity at approximately 425 nm.A partial vibrational analysis of this emission is presented and it is concluded that the emitting species is the FCO radical, as previously suggested.A comparison is made between the enthalpy changes of the primary reactions between ozone and the fluoroethenes and their correlation with the identity of the emitting species.The exothermicity of the reaction correlates with the chemiluminescent reaction channel.
