Abstract
Chemiluminescence from the reactions of Ba ground state 6s2 1S and metastable 6s5d 3D atoms with NO2, N2O, and O3 has been studied under single‐collision conditions. Spectra, chemiluminescence cross sections, and photon yields for production of BaO* are reported. In the Ba(3D)+N2O and Ba(1S, 3D)+O3 reactions, a red feature, not previously reported, has been observed and tentatively assigned as BaO D 1Σ+–A 1Σ+ emission. The dynamics of these reactions and the differences between the Ba and lighter alkaline earth atom reactions are discussed.Keywords
