Direct photolysis of tetrafluoroethylene at 1849 Å

Abstract

The photolysis of C2F4 at 1849 Å gives the following products, whose quantum yields are strongly dependent on substrate pressure: C2F6, C2F2, cyclo-C4F8, cyclo-C3F6, C3F6, C3F8, and polymer.The primary photochemical reactions are tentatively identified, and involve double bond fission and fluorine molecule and fluorine atom elimination.
