Abstract
Electronically excited lead atoms, Pb(61D2), have been generated by the pulsed irradiation of lead tetraethyl in the presence of helium buffer gas and monitored photoelectrically in absorption by time-resolved attenuation of atomic resonance radiation at λ= 374 nm (7s(3P° 2)â†�62 p(1D2)). The decay of the excited atom in the presence of added gases has been investigated and rate constants for removal are reported for the following collision partners: He, Xe, H2, N2, O2, CO, NO, CO2, N2O, CH4, C2H4, C2H2, CF4, SF6 and PbEt4. The rate data are compared with those for C(21D2).
