The high-temeperature AlF+ radical cation has been generated by the photoionization of AlF(g) produced both by a laser sputtering method and high-temperature vaporization reactions.This represents the first spectroscopic study of AlF+/sup

Rate constants as a function of temperature for the reaction Al + SF6 have been measured under pseudo-first-order conditions. Laser-induced fluorescence was used to monitor the relative concentrations of either the reactant Al or the primary pr

Matrix isolation has been used to study the photolytically induced reaction of AIX (X = F, Cl, or Br) with 02. The peroxo and bisperoxo compounds XAIO2 and XAI(O2)2 are found to be the products of these reactions. While the peroxo species XAIO2 were already addressed in a separate work, we concentrate herein on the bissuperoxo complexes XAI(O2)2, which are to our knowledge the first examples of such complexes with Al centers. Our IR spectroscopic results taking in the effect of isotopic substitution (16O/18O) allied with quantum chemical calculations show that the O2 moieties in these complexes are side-on coordinated, leading to an overall C2v symmetry of the complexes and a spin multiplicity of 3. The O-O distance of about 1.366 A argues for the presence of superoxide units. The force constants are, however, somewhat smaller than expected for a superoxide anion and indicate that the bonding in the complexes cannot be described simply on the basis of an ionic model. Interestingly a photoinduced intramolecular isotopic scrambling process is observed for the compounds resulting in partial conversion of the XAl(16O2)(18O)2 isotopomer into XAl(16O18O)(16O18O). The properties of the complexes will be compared to those of complexes to transition metal centers.
