Spectroscopy and Kinetics of Lead Oxide Chemiluminescence.

Abstract : Chemiluminescence from lead oxide has been observed from the reaction between lead (Pb) vapor and 02(1 delta). The spectrum obtained from this emission has been compared to that obtained from the chemiluminescence observed during the reaction between Pb and ground state 02(3 sigma). A significant enhancement of the A and B states over the a state was noted. Spectral analysis has led to the assignment of 225 transitions from the a, b, A, B, C, C', D and E excited states to the ground state. A simple kinetic analysis was performed for the two reactions in which a plot of the logarithm of the intensity of a spectral band vs 1/T K was prepared. From the slope of the straight lines produced, the activation energies of the two reactions were calculated.
