用串级飞行时间质谱(Tandem TOF)仪研究了激光蒸发方法产生的苯甲酸钠及裂解产物团簇离子的形成和可能的构型。通过对苯甲酸钠团簇离子的紫外光解的研究, 决定了反应通道及分支比, 并定性地讨论了其结构特征。

关键词: 激光蒸发, 苯甲酸钠, 团簇, 紫外光解

Laser ablation of sodium benzoate was investigated in tandem TOF mass spectrometer to determine the formation and morphology of cluster ions produced. UV photolysis of cluster ions of sodium benzoate was investigated in the second mass spectroscopy by Tandem TOF to determine the reaction channel and branch ratio, and discussed qualitively on morpholpgy.

Key words: LASER EVAPORATION, SODIUM BENZOATE
