Size Dependence of Chemical Reactivity of Gaseous Metal Clusters, A New Mechanistic Probe.

摘要

The determination of the mechanisms of chemical reactions leading to the formation of different types of materials is one of the principal occupations of many chemists today. To accomplish this, the dependence of the observed transformation is studied as a function of a number of intensive variables such as temperature, pressure, concentration of reactants as well as the hydrogen ion concentration of the solution. In this account, we summarize recent studies in which the observed changes of the chemical reactivity of gaseous niobium clusters with size was used as a new degree of freedom that assists in deducing the mechanism of the chemical reactions studied.
