✦ Synopsis

The title reaction has been studied with picosecond resolution at energies near threshold. Expansion cooled nitrate radicals were photoexcited to admixtures of *E' and ground state 'A; levels, ensuring a unimolecular decomposition mechanism. NO was monitored by LIF. The dissociation rate is = 1 XIOgs-' just above the 16800 cm-' NO+O, barrier and increases rapidly with energy, reaching 5.5 x log s-i at 17040 cm-'. A marked signal decrease at higher energies is attributed to NO2 + 0 dominating above its thermodynamic threshold. These observations support three-center NO + Or formation via 'A;.

Recent experimental results on the thermal decomposition of N205 in N2 are evaluated in terms of unimolecular rate theory. A theoretically consistent set of fall-off curves is constructed which allows to identify experimental errors or misinterpretations. Limiting rate constants k o = "21 2.2 X lo-:
