✦ Synopsis

The gas phase reactivity of Fe(aSDs) with N20 in the temperature range 398-620 K is reported. Iron atoms were produced by the photodissociation of ferrocene and detected by laser-induced fluorescence. The reaction rates of the a 5D s states are very slow and temperature dependent. The bimolecular rate constant is described in Arrhenius form by (1.41 -t-0.29)× 10-10 exp(-44.4 + 1.0 kJ/mol/RT) cm 3 s-1 where the uncertainties are + 2or. The disappearance rates in the presence of N20 are independent of buffer gas identity (Ar or N 2) and total pressure. The removal rate constants for the a 5Dj states are independent of J.
