Abstract:
NO2 has been electronically excited to the 2B2/2B1 states, using pulsed dye laser radiation at 400–500 nm. Strong mixing of the electronically excited state with the ground electronic state (2A1) leads to highly vibrationally excited NO2(2A1), from which infrared emission has been observed. The time dependence of the IR fluorescence at several wavelengths has been observed, and quenching rate constants for NO2 and other gases have been measured. In addition to IR fluorescence at wavelengths identifiable as vibrational transitions (3.0–4.0, 6.1–6.8, 7.4–8.5, and 10.0–14.0 μm), emission at wavelengths & lt;3.0 μm has been observed and attributed to a transition with electronic character. The emission observed in these experiments has been compared with that of chemiluminescent NO2 produced in the O+NO and O3+NO reactions.
