Research output: Contribution to journalArticlepeer-review


The rate constant for NO+(υ) vibrational relaxation by metastable O2(1Δg) molecules is found to be (3±2)×10-10 cm3 s-1 at room temperature, in contrast to the lack of vibrational quenching of NO+(υ) by ground-state O2(3Σ) molecules, for which the quenching rate constant <10-12 cm3 s-1. This suggests that NO+(1Σ)+O2(1Δ) follows a much more attractive potential curve than NO+(1Σ)+O2(3Σ).
