Abstract

The photoionization and photodissocn. of vinyl chloride have been performed by synchrotron radiation. The ionization potential of C2H3Cl and appearance potentials of fragment ions have been measured. The ionization potential of C2H3Cl is 10.03 ?0.01 eV and the dissociation energies D0(C2H2Cl-H), D0(C2H2Cl+-H), D0(C2H2Cl-H+), D0(C2H3-Cl) and D0(C2H3+-Cl) are 5.09 ?0.05, 5.02 ?0.08, 8.66 ?0.05, 3.64 ?0.10, 2.56 ?0.05 eV resp.

Key words: REACTION MECHANISM, CHLOROETHENE, PHOTOIONIZATION, DISSOCIATION ENERGY, SYNCHRONOUS RADIATION
