摘　　要：在自制的分子束多光子电离飞行时间质谱仪上研究了叠氮甲烷在355nm的多光子电离与解离;在气相池里得到了该分子在激光波长为410—510nm的共振多光子电离谱.根据实验结果,提出了叠氮甲烷的多光子电离与解离机制;根据里德堡公式,归属多光子电离光谱为里德堡态3p、3d、4s、4p和5s的跃迁.The muiltiphoton ionization and dissociation of methyl azide at 355 nm was studied experimentally on a home-made molecular beam laser multiphoton ionization time-of-flight mass spectrometer. The Resonant multiphoton ionization Rydberg spectra of the same molecule was also recorded in a gas cell. Based on our results an ionization/disso-ciation mechanism for the observed rich fragment ions has been proposed. 3p,3d,4s,4d and 5s Rydberg states are assigned in the spectrum according to Rydberg formula.
