Abstract

From the reaction of Pb with metastable oxygen O₂(¹Δ_g) in a Broida type oven we have analysed at high resolution some vibrational levels of the X0⁺, a1, A0⁺ and B1 states of the ²⁰⁸PbO molecule. The rotational parameters determined allowed us to recalculate the position of the various isotope lines to within 0.01 cm^-1. We have found a negative value of ω_eχ_e (-0.123 (25) cm^-1) in A0⁺, contrary to previous observations. The Ω type doubling in a1 varies from +1.8 × 10^-4 cm^-1 (υ′ = 2) to +2.3 × 10^-4 cm^-1 (υ′ = 9) and in B1 from -1.17 × 10^-4 cm^-1 (υ′ = 0) to -0.97 × 10^-4 cm^-1 (υ′ = 2).
