The gas-phase reactions of ground and excited state Ni+ with CH3X and CF3X (X=Cl, Br) were examined in a selected ion drift cell apparatus.  Ni+ was prepared in a glow discharge utilizing either Ne or Ar as the working gas.  State-specific product formation was determined using electron state chromatography.  These experiments indicate that Ni+ is produced in both the ground state as well as a distribution of excited states.  Ground state Ni+ produces association products exclusively while, dependent on energetic and spin requirements, certain Ni+ excited states exhibit bimolecular chemistry, including X-abstraction and charge-transfer.  All four reactions indicate the presence of reactive Ni+ excited states; however, kinetic measurements suggest that unreactive states also occur. The behavior of Ni+ produced in Ar and Ne discharges is not influenced by the identity of the discharge gas; however, the proportion of reactive excited states may be influenced by other discharge parameters.
