Quenching of by O(3P), O2(a1Δg), and other gases

Abstract

Spectroscopic and kinetic results for the quenching of [Formula: see text] are presented, including the first reported laboratory observation of gas phase emission from vibrational levels greater than zero for this state. In addition, the absolute rate constants for quenching of the lowest vibrational level by O(3P), O2(a1Δg), [Formula: see text], CO2, SF6, HE, and Ar are given. These results are compared with the results of atmospheric modeling studies. Qualitative evidence is presented for the formation of O2(a1Δg) and [Formula: see text] in the quenching of this state.
