✦ Synopsis
Rate constants for the recombination reaction OD + NO, + M-DNO, + M have been determined in the falloff region (5-500 torr) and a t 297 -C 2 K, in the presence of He, N,, and SF, as third bodies, by using a pulsed laser photolysis-resonance absorption technique. Values of KO, k x and the falloff parameter F, have been estimated. Our rate constants were, within the experimental uncertainty, the same as those reported for the reaction of OH radicals with NO,.

Absolute rate constants for the reaction OD + DNOJ have been determined at 297 + 2 K, using a pulsed laser photolysis-resonance absorption technique. The values (in cm3 mol-' s-l) obtained for DN03 alone and in the presence of 107 Torr SF, and at + 3a are (5.47 zb 0.75) x lo9 and (8.51+ 0.72) x lo9
The reactions Br + NO2 + M -+ BrNOZ + M (1) and I + NOz have been studied at low pressure (0.6-2.2 torr) at room temperature and with helium as the third body by the discharge-flow technique with EPR and mass spectrometric analysis of t h e species. The following third order rate constants were fou
The gas-phase reaction of the NOa radical with NO, was investigated, using a flash photolysis-visible absorption technique, over the total pressure range 25-400 Torr of nitrogen or oxygen diluent a t 298 2 2 K. The absolute rate constants determined (in units of em3 molecule-' s-') a t 25, 100, and
The termolecular rate constant for the reaction C1 + NO, + M has been measured over the temperature range 264 to 417 K and at pressure 1 to 7 torr in a discharge flow system using atomic chlorine resonance fluorescence at 140 nm to monitor the decay of C1 in an excess of NO,. The results are ky = 9.
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-:
