Experimental and theoretical investigations of the structure and the stability of the BNSi molecule

“…29 Our computed ⌬ a H 0 o (BNSi,g) of 1017 kJ mol Ϫ1 is about 6% smaller than the experimental value, obtained in the present investigation.…”

Structural properties of nanoclusters: Energetic, thermodynamic, and kinetic effects

“…15. There, plotted, besides their results at large sizes, E b for smaller clusters (N ≤ 7) obtained from the results of other groups (Fuke et al, 1994;Jarrold and Honea, 1991;Schmude et al, 1995Schmude et al, , 1993. Three regimes are clearly shown.…”

“…The black circles are data for neutral silicon clusters obtained from the collision-induced dissociation experiments by Jarrold and Honea (1991) on the corresponding silicon cluster cations taking the experimentally determined photoionization potentials into account as from Fuke et al (1994). The black triangles belong to the Knudsen mass spectrometric measurements of Schmude et al (1995Schmude et al ( , 1993. The crossover from elongated to the spherical neutral silicon structures can be estimated from the binding energies to be located around N = 25.…”
