Abstract

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)_m⁺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.

Key words: Synchrotron radiation, Cluster ions, Ion-molecule reactions within clusters, Photoionization, Vinyl chloride/acetonitrile
