借助质量分析离子动能谱和串联质谱研究了由电子轰击产生的双电荷离子的单分子亚稳碎裂及碰撞诱导分解过程,讨论了两种实验方法导致的差别因素.此外,根据质量分析离子动能谱提供的双电荷离子电荷分离反应的动能释放值计算了两电荷中心间距的最小值,以判别按不同电荷分离方式碎裂的双电荷离子的过渡态结构.
Single-molecule metastable fragmentation and collision-induced decomposition of double-charged ions generated by electron bombardment were studied by means of mass spectrometry and tandem mass spectrometry, and the differences caused by the two experimental methods were discussed. In addition, the ion kinetic energy The kinetic energy release value of the double-charged ionic charge separation reaction provided by the spectrum was calculated as the minimum of the two charge-center spacings to determine the transition state structure of the double-charged ions fragmented by different charge-separation methods.
