二乙胺分子的多光子电离:"梯转换"过程 总被引:1,自引:0,他引:1
The multiphoton ionization (MPI) of diethylamine is first reported in this paper. A time-of-flight mass spectrometer was used in the experiment under collision-free condition. MPI mass spectra were measured in the region of 464 ~486 nm using a dye laser and at double frequency of a Nd:YAG laser. Molecular ion was created through resonance enhanced multiphoton ionization (REMPI) via Rydberg states. Fragment, ion distribution was formed through “ladder switching” process. The experimental demonstration of the process is reported for the first time by the discussion of dependence of ion relative, abundance on laser wavelength and energy. The competition between further up-pumping and fragmentation of Parent ion also exists, and higher laser intensity favors the former. 相似文献
