✦ Synopsis

The internally cold, gas-phase electrostatic complex of Ni+ with a single carbon dioxide molecule, Ni+.OCO, is observed by resonant photodissociation spectroscopy with visible light. Sharp bound-bound optical absorptions are detected via predissociation into Ni+ and CO2 fragments. A cutoff in the photofragmentation is observed below 17 100 cm-' and this represents the threshold for dissociation into the lowest quartet pathway. This places the binding energy of the Ni+.OCO complex at 1.08 IL 0.01 eV with respect to ground state Ni+ and COz.

The site conversion ofadsorbed CO between the terminal site and the bridged site on Ni ( 100) was studied by means of infrared reflection absorption spectroscopy. The temperature dependence of the relative occupation for two sites was measured from 80 to 220 K in detail, where the binding-energy dif

Ni,Ar+ ions generated in a laser-driven plasma/supersonic expansion are photodissociated at different photon energies. This weakly bound ion fragments into primarily Ni: ( +Ar) at 3.0 eV and into Ni' (+Ni t Ar) at 3.5 eV indicating the Ni-Ni+ bond dissociation energy is between these limits.
