Complete kinematic measurement of three-body reaction dynamics: Dissociative photodetachment of O6− at 532 nm
摘要:
Measurement of the translational energy partitioning in the three-body dissociative photodetachment of O6− (O6−+hν→O2+O2+O2+e−) at 532 nm is reported. Using photoelectron and photofragment translational energy spectroscopies in coincidence, a complete kinematic measurement of the three-body dissociation of neutral O6 is obtained. Vibrationally resolved product translational energy distributions are observed. The results provide insights into the structure, binding energy, and dissociation dynamics of O6− and O6 and illustrate a new approach to the study of three-body reaction dynamics.
Infrared spectra of cyclic-O6+ and trans-O6+ in solid neon and argon
摘要:
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.

Waals clusters. The appearance energy AE of ((O2)n· O)2+ is shifted well below the appearance energy of O2+ from O2. This is in accordance with a recently suggested sequential ionization mechanism for the production of stable doublychargedcluster ions. Moreover, the shape of the ionization cross section curve of singlychargedcluster ions indicates that above the appearance energy of doubly charged
