Determination of the absolute second-order rate constant for the reaction Na + O3→ NaO + O2

Abstract

The absolute second-order rate constant for the reaction Na + O3→NaO + O2(k1) has been determined by time-resolved atomic resonance absorption spectroscopy at λ= 589 nm [Na(32PJ)â†� Na(32S1/2)] following pulsed irradiation, coupled with monitoring of O3 by light absorption in the ultra-violet; this yields k1(500 K)= 4(+4,–2)× 10–10 cm3 molecule–1 s–1, resolving large differences for various estimates of this important quantity used in modelling the sodium layer in the mesosphere.
