【Abstract】 Photoionization of CH₃CN/C₃H₃Cl complex system is proceeded by synchrotron radiation single photon in a diameter 70μm cw supersonic jet with a quaduapole mass spectramer, The cluster ions（CH3CN ）m（C2H3Cl） are observed. The C2H3ClCN+ ion（m/e=88）, whose mass peak is high, is produced by ″intramolecular″ion-molecule reactions withinionized clusters, The heat of the exothermic reaction makes the bond H3C&CN broken.The result of ab initio calculation demonstrates that the C2H3ClCN+ ion is stable. Photoionization efficiency curves and ionization potentials are obtained.更多还原
