  Study of the reactions N⁺₂+2N₂→N⁺₄+N₂ and O⁺₂+2O₂→O⁺₄+O₂ from 20 to 160 K by the CRESU technique

  摘要：

  Rate coefficients k1 and k2 have been determined for the association reaction N+2+2 N2→k1N+4+N2 and O+2+2 O2→k2O+4+O2 in the temperature range 20–160 K, using a supersonic jet apparatus (CRESU), which is described in detail. For the highest temperatures where other measurements exist, the measured values of the rate coefficients are in excellent agreement with previous measurements. The temperature dependence of k1 can be represented by a power law of the form k1=6.0×10−29 (300/T)1.85 from 20 K to higher temperatures. For k2, only lower limits for 20 and 45 K are reported but the present data do not confirm the existence of a maximum in k2 as suggested by other authors. These results are examined in the light of recent theoretical arguments.

  Charged transient species in the oxygen system have been trapped in solid argon and neon using electron impact, Townsend discharge, and laser-ablation methods. The previously identified O3−, O4−, and O4+ species are observed in these experiments. Absorptions at 1435.0 and 1429.5 cm−1 in solid neon are characterized as cyclic-O6+ and trans-O6+, respectively, on the basis of annealing behavior, isotopic substitution, multiplet structure in mixed O216+18O2 experiments, and density functional calculations. Cyclic-O6+ is observed at 1416.1 cm−1 in solid argon, a smaller displacement than found for cyclic-O4+ in solid argon.
• A determination of the stabilities of O⁺₂(O₂)_<i>n</i> and O⁻₂(O₂)_<i>n</i> with <i>n</i>=1–8 from measurements of the gas‐phase ion equilibria

  The gas-phase equilibria of solvation reactions of O+2 and O−2 ions with O2 were measured with a pulsed electron-beam high-pressure mass spectrometer. van’t Hoff plots of the equilibrium constants lead to the determination of the thermochemical stabilities for O+2(O2)n with n=1–8 and for O−2(O2)n with n=1–7. The fashion of the bonding in the clusters O+2(O2)n and O−2(O2)n changes drastically from covalent to electrostatic one between n=2 and 3, and n=1 and 2, respectively. That is, the first shells formed for these positive and negative cluster ions are O+2(O2)2 and (O2---O2)−. The formation of the second shells, O+2(O2)2(O2)2 and (O2---O2)−(O2)2, are also observed, but they are only slightly more stable than larger clusters toward dissociation.
