Abstract

The adsorption of gas phase molecules on transition metal clusters is fundamentally important in basic science and practically vital in new functionality material and devices. On page 1854, J. Wang et al. report both molecularly and dissociated species of N2 and NO adsorbing on different-sized vanadium clusters. The adsorption of the two molecules shows quite different size-dependent behaviors: The adsorption energies for N2 exhibit clear size dependent variations, whereas, for NO, there are only trivial fluctuations; N2 plays an attenuation role on the magnetism, while NO can either reduce or increase the magnetic moment of vanadium clusters.
