The photoionization and photodissociation of C2HCl3 by vacuum ultraviolet (VUV) photons from synchrotron radiation source were investigated under the supersonic beam conditions by using a reflectron-time-of-flight mass spectrometer (TOF-MS). The photoionization mass spectrum and the photoionization efficiency (PIE) curves of the parent ion and some fragment ions were measured. The ionization energy of C2HCl3 was measured to be 9.51±0.05 eV. The potentials for the appearance of C2HCl+2, C2HCl+, and CCl+ are obtained to be 12.40±0.05, 15.88±0.05, and 18.33±0.05, respectively. The formation enthalpies of some major ions and the dissociation energy (DE) of C2HCl3 have been evaluated from these data. According to the experimental results and the theoretical calculations by G1 theory, the main possible channels of dissociative photoionization of C2HCl3 have been discussed. In the future, one can detect C2HCl3 with SPI-TOFMS technique using 118.0nm laser. Based on the mass spectrum obtained at that wavelength using synchrotron radiation source.
