Structure and reactivity of Nin (n=7–14, 19) clusters
Abstract
Results of a computer simulation study of Nin (n=7–14, 19) clusters, their structures, energetics, and reactivity with a D2 molecule are presented. The clusters are described by an embedded atom potential, whereas the interaction between the molecule and the clusters is modeled by an LEPS (London–Eyring–Polanyi–Sato) potential energy function. The focus is on structures of the clusters and their reactive channels. The total numbers of stable isomers of the clusters are obtained by sampling their phase space, and the isomers' energy spectra are determined. On the reactive side, dissociative chemisorptions cross sections and decay-rate constants are calculated. © 2001 John Wiley & Sons, Inc. Int J Quantum Chem 84: 208–215, 2001
