摘要

The gas phase reactivity of Mn(a(6)S(5/2)) with N2O in the temperature range 448-620 K is reported. Manganese atoms were produced by the photodissociation of 2-methylcyclopentadienyl manganese tricarbonyl and detected by laser-induced fluorescence. The reaction rate of the a(6)S(5/2) state is very slow and temperature dependent. The rate constants are independent of total pressure indicating a bimolecular reaction. The rate constants are described in Arrhenius form by (2.05+/-0.45)x10(-10) exp(-44.7+/-1.0 kT/mol/RT) cm(3) s(-1). (C) 1996 American Institute of Physics. [References: 17]
