✦ Synopsis

For the 'title reaction, the pressure dependent rate coefficients were studied at 298 K using two complementary experimental techniques. Pulse radiolysis combined with UV absorption was employed at pressures between 500 and 1000 mbar, while a fast-flow system with a quadrupole mass spectrometer (at low ionization energies) was applied at pressures in the range of 0.7-5.1 mbar. The fall-off curve was constructed in terms of Troe's analysis, and the following high-and low-pressure limiting rate coefficients were derived: krec,~ = (1.3 + 0.3) X 10-1o ),( (T/300)o.42 cm 3 molecule-1 s-1 and krec,o/[He] = (1.8 _ 0.5) × 10 -27 X (T/300) -3"85 cm 6 molecule-2 s-1.
