Abstract
The photolysis of vinyl fluoride at 1470 Å and pressures in the range 1–150 torr, yields in addition to C2H2 and C2HF, 1,1-C2H2F2. The yield of 1,1-C2H2F2 with respect to that of C2H2, increases rapidly with decreasing pressure. It is proposed that F atoms are liberated as a result of the decomposition of certain excited C2H3F molecules. The F atoms in turn react with C2H3F to give a chemically activated difluoroethyl radical with a small excess energy with respect to a decomposition which yields almost exclusively 1,1-C2H2F2. The details of this preliminary proposal are discussed in relation to the measured relative yields of C2H2, C2HF, and 1,1-C2H2F2.Keywords
