Spectroscopic Analysis of PbO Chemiluminescence.
Abstract
A lead oxide (PbO) flame was generated in a flow tube reactor by reacting lead vapor generated in a furnace with the oxidizers O2 and N2O. The emissions from the chemiluminescent flames were analyzed by means of a Jarrell Ash 0.25 m spectrograph and photomultiplier operating in the region 2000-8000 A. Rovibronic bands assignable to the x-a, x-b, x-A, x-B electronic systems were observed. The assignments compare well with published work. Spectra obtained with the two different oxidizers were compared. Significant differences in spectral line intensities were recorded. The pressure dependence of the intensities was also measured. Again, significant differences were recorded when the two different oxidizers were used. In the Pb + O2 reaction a low pressure enhancement of various lines was observed. Significant differences between the chemistry of these low pressure reactions and the chemistry of similar reaction of high pressure were observed. (Author)
