摘要: 在原子束装置上测量了Pb和放电氧、O_2(1Δ)反应的化学发光光谱, 获得了一些新的谱带, 并观测了氧气压力对化学发光光谱的影响。当观测区的压力大于2.5×10~(-3)Torr时, 发现B~(3Π)-X~(1Σ~+)谱带系的(3,0)、(4,0)两个振动带的强度显著增强。分析表明这新的光谱现象是a~(3Σ~+)态和b~(3Σ~+)态的PbO分子与O_2(1Δ)分子的E-E近共振传能以及PbO分子的不同电子态的微扰结果。

Abstract: The chemiluminescent spectra of the reactions of Pb with discharged oxygen, O_2(1Δ), have deen measured in an atomic beam apparatus, and some new bands have been obtained, When the presure of the observed region was larger than 2.5× 10~(-2) Torr, the intensities of the(3,0) and (4,0) viberational bands of the B~3Π-X~1Σ~+ transition were enhanced remarkedly, this can be interpreted with the aid of the processes of the near-resonance collision transfer energy between PbO and O_2 (1Δ) as well as the collision induced in tramolecular energy transfer of PdO.
