, p. 5517 - 5524 (2007/10/03)
The title reactions of ground-state lead atoms have been studied in isolation in an HTFFR (high-temperature fast-flow reactor) at pressures in the 10-150 mbar range. Pb consumption rate coefficients were determined using atomic resonance absorption spectr

The reactions of Pb atoms with molecular reagents F2 and Cl2 have been studied in a molecular beam apparatus by laser fluorescence detection of PbF and PbCl products.The experiments were performed in a beam-gas configuration under single-collision conditions.The PbCl product from Pb + Cl2 was observed in the vibrational levels υ17 of the ground Χ1 electronic state.The PbCl product vibrational state distribution was derived; the average vibrational excitation was found to be 21percent of the total available energy.For Pb + F2, PbF(Χ1) product was detected in only the υ = 0 and 1 vibrational levels, and the rovibrational state distribution could be characterized by a 300 K Boltzmann distribution.By modulating the Pb beam, it was concluded that this observed product was an artifact and did not arise from bimolecular gas-phase collisions.The radiative lifetimes of the PbF(A,B) and PbCl(A) states were also measured and were also measured and were found to equal 4.9 +/- 0.3 μs, 10 ns, and 1.14 +/- 0.06 μs, respectively, averaged over the observed vibrational levels.
