Abstract: The photoionization curves for vinychloride and its abundant fragment ions, es-pecially (C_2H_3)~+ and (C_2H_2)~+, have been measured with synchrotron radiation in the photon energy range from 8-20eV on the photochemistry station at HESYRL. The structure of the photoionization efficiency curves(PIE) for(C_2H_3)~+ and (C_2H_2)~+ were firstly exhibited and explained by the vertical ionization potentials in terms of different ionization processes.
