The rotationally resolved photodissociation spectrum of mass-selected Ni~ has been observed. Much of the spectrum is congested and perturbed, making the assignment of spectroscopic constants difficult. However, the use of an accidental perturbation in the upper state is shown to simplify the interpr

โฆ Synopsis
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.

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 1723
