Abstract: The photoionization and photodissociation processes of C2Cl4 were investigated under the supersonic molecular beam conditions by using a reflectron-time-of-flight mass spectrometer (TOF-MS) and vacuum ultraviolet (VUV) photons from synchrotron radiation source. The photoionization mass spectrum and the photoionization efficiency (PIE) curves of the parent ion and some fragment ions were measured. The appearance potentials of these ions are obtained from their PIE curves. The formation enthalpies of some major ions and the dissociation energy of C2Cl4 have been evaluated from these data. According to the experimental results and the energy calculated by G1 theory, the main possible channels of dissociative photoionization of C2Cl4 have been discussed. In the future, we can detect C2Cl4 with single photon ionization(SPI)-TOFMS technique using 118.0nm laser radiation. This is based on the mass spectrum obtained at the wavelenth by using synchrotron radiation source.
