✦ Synopsis

The electrostatic complex of Ni+ with a single nitrous oxide molecule, Ni+. N,O, has been studied by resonant photodissociation spectroscopy. Optical absorptions are detected via predissociation of the ion into Ni+ and N,O fragments. A cutoff in the resonant photofragmentation is observed below 17230 cm-' which represents the threshold for the lowest quartet dissociation pathway. This places the binding energy of the Nif. N,O complex at 1.096 f 0.003 eV. The binding energy of this complex is only slightly greater (= 16 meV) than that of the similar compound, Ni+. CO,. Speculation is presented supporting a T-shaped ground state geometry in both species.

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.
