Abstract

The lifetime of the BaO C ¹Σ⁺ state is investigated for several vibrational and rotational levels at 1 Torr and under molecular beam conditions. A collision free radiative lifetime of 10.5 ± 1 nsec is observed for the υ = 0 level. Dispersed fluorescence from υ = 0, 1, and 2 to various low lying electronic states is measured and used to obtain electronic dipole transition moments of: μ_C-X² = 9.9D², μ_C-A² = 16.8D², μ_C-A² = 9.8D², μ_C-b ² = 3.1D², μ_A-X² = 3.2D ², μ_A-X² = 0.14D².
