Evidence of structural isomerism in small niobium clusters

This is the authors' abstract. We don't add key points for this paper.

The reactivity of Nb clusters with nitrogen and deuterium was studied using a pulsed laser vporization source coupled to a fast flow reactor. The relative reactivity of the various clusters was determined by monitoring the depletion of the cluster ion signal as a function of reactant flow rate. A kinetic analysis of the chemisorption is given. The geometrical isomerism of the cluster ions and its relationship to reactivity is discussed.(AIP)
