Abstract
C2F3Cl is photolyzed with a TEA-CO2 laser at 1050.44 cm−1 with focussed fluences up to 280 J/cm2. The stable products in the IRMPD of C2F3Cl are determined for up to 10 Torr of C2F3Cl being photolyzed both neat and with added O2. C2F4 and trans-C2F2Cl2 are found to occur in the greatest yield though C3F5Cl, C3F4Cl2, C4F7Cl, and C2F3Cl3 also appear to be primary products. When O2 is present F2CO, FClCO, and CF2ClCOF are the exclusive products. The formation of these products are for the most part consistent with a carbene formation dissociation mechanism for C2F3Cl IRMPD. C2F3Cl3 may best be explained by another mechanism competitive with carbene formation. Many products attributed to secondary photolysis mechanisms are observed for long photolysis times.
