【摘要】 利用多光子电离与飞行时间质谱相结合的方法,分析了乙胺分子在355nm激光作用下的电离信号随激光强度的变化。在355nm激光作用下,随着激光强度的增加,母体离子和大质量离子的信号逐渐减弱,小质量的离子信号逐渐增强,分析了乙胺分子在355nm激光作用下的解离过程。更多还原

【Abstract】 The MPI mass spectrometry of ethylamine was studied at 355nm.Under 355nm laser,the mother ion intensity of methylamine decreases,and further disappeares with the increasing of laser energy.The intensity of ions with larger mass trails off,but the smaller mass ions intensity increases highly.更多还原
