Abstract

The rate constant for NO⁺(υ) vibrational relaxation by metastable O₂(¹Δ_g) 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).
