摘要: 利用同步辐射和超声射流技术产生了团簇离子(CH3CN)m+(C2H3Cl)(m≤4,n≤4)及C2H3ClCN+,C2H2ClCN+由(CH3CN)(C2H3Cl)+经团簇内离子。分子反应生成,反应过程中放出能量使H3C-CN键断裂。ab initio计算表明C2H3ClCN+离子是稳定的。同时测得了它们的电离势。

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.
