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 multi-photon ionization and dissociation of azidomethane at 355 nm were studied by a self-made molecular beam multiphoton ionization time-of-flight mass spectrometer. Resonance multiphoton ionization spectra of the molecule at 410-510 nm were obtained in a gas phase cell. According to the experimental results, the multi-photon ionization and dissociation mechanism of azidomethane is proposed. According to the Rydberg formula, the home multi-photon ionization spectra are the transitions of 3p, 3d, 4s, 4p and 5s of Rydberg states.
