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.
