A reanalysis is summarized of a previously unquestioned, sole source o
f kinetic data, on the reaction of NaO with O-atom. It is apparent tha
t there are significant uncertainties in the kinetic mechanism of the
experiments. Moreover, it appears plausible that these reaction rate d
ata do not relate to NaO but rather to Na2O. This conclusion has the p
otential for resolving a dilemma concerning the chemiluminescent excit
ation mechanism of sodium in the airglow and in long duration meteor t
rails. It remains conceivable that Chapman's originally suggested sche
me is valid and recently proposed alternative explanations invoking a
role for NaO(A2SIGMA+) are unnecessary.
