Single vibronic emissions from NO B 2Π (v′ = 7) and O2 B 3Σ−u (v′ = 4) excited by 193 nm ArF laser

Single vibronic emssions of NO B 2Π(v′ = 7)→X 2Π(v\) and of O2 B 3Σ−u (v′ = 4)→X 3Σ−g(v\) are generated following irradiation of NO and O2, respectively, by a 193 nm ArF laser. Both emission processes compete with predissociation of the excited states. The aborption of the laser radiation will be discussed in detail. (AIP)
