“…Clusters have been drawing a great deal of attention since clusters link the gap between isolated molecule and bulk material. Clusters containing III−V group elements such as GaAs, − BN, − AlP, , and InP have been studied extensively due to their distinctive properties as precursors for bulk semiconductors. Among them, GaAs clusters have received much more attention due to the obvious technological importance.…”

“…Many workers have performed experiments to detect various BN cluster ions by applying intense laser to BN powders. − B x +1 N x + ( x = 1 − 8) series were detected when the supersonic expansion technique was employed to cool down the generated hot plasma . Roland and Wynne also carried out photoionization and photofragmentation of B x +1 N x ( x = 1 − 8) and found that the abundance of B x +1 N x + increases as the laser intensity increases …”

The structures and energies of low-lying electronic states of AlN3, Al3N, and Al2N2 have been evaluated at the HF, MP2, QCISD(T), CCSD, and CCSD(T) levels of theory, using the several basis sets of 6-31G* (for HF), cc-pVDZ (for MP2 and QCISD(T)), and cc-pVTZ (for CCSD and CCSD(T)). The ground state of AlN3 is predicted to be a 1Σ+ state with a linear Al−N−N−N structure. The most stable species of Al3N is found, however, to have D 3 h symmetry and 1A‘1 ground state. For Al2N2, various isomers are found to be energetically favorable. A rhombic isomer with the nitrogen atoms along the short diagonal and with a 1Ag electronic state is the lowest in energy at the MP2/cc-pVDZ, QCISD(T)/cc-pVDZ, CCSD/cc-pVTZ, and CCSD(T)/cc-pVTZ levels. A linear structure Al−N−N−Al with a 3 electronic state is the second lowest. The third stable isomer with the aluminum atoms bonded directly to the N2 π orbital seems to be one of the model species for the sake of the nitrogen fixation. Our results suggest that the formation of a variety of the configuration of Al2N2 is energetically plausible under the reaction conditions employed since the energy differences in the Al2N2 species are relatively small.

“…4,5 Different techniques have been applied to study boronnitrogen containing molecules. Becker et al 6,7 used laser ionization mass spectrometry to study the formation of B n N m ϩ clusters ions in a laser plasma. They observed that for B n N nϪ1 ϩ and B n N nϪ2 ϩ cluster ions there is an alternating abundance distribution with the higher intensities of the cluster ions with the odd number of atoms.…”

High-temperature Knudsen cell mass spectrometry has been used to study the equilibria involving the B2N molecule over the Si–BN system. Thermal functions needed in the evaluation of the mass spectrometric equilibrium data have been calculated from available experimental and theoretical molecular parameters. The enthalpy changes for the reactions 2B(g)+Si2N(g)=B2N(g)+2Si(g), and BN(s)+B(g)=B2N(g) have been measured. The following atomization enthalpy, ΔaH0o, and enthalpy of formation, ΔfH298.15o, in kJ mol−1, of 1045.5±18 and 551.3±18 for the B2N molecule have been determined from these reaction enthalpies. Atomization energies of similar molecules have been compared and discussed.
