The potential energy surfaces of N-8 clusters were investigated by density
functional theory (DFT) and a possible synthesis reaction pathway for N-8 (
C-S) was suggested. the species involved were fully optimized up to the B3L
YP/6-311+G* level of theory. Relative energies were further calculated at t
he QCISD/6-311+G*//B3LYP/6-311+G* level. The reaction rate constants of the
se steps from the 1 (N-5(+) . . .N-3(-), complex, C-S) to 2 (N-8, C-S), 2 (
N-8, C-S) to 3 (N-8, C-S), 3 (N-8, C-S) to 4 (N-8, D-2d), and 4 (N-8, D-2d)
to 5 (N-8, C-S) reactions were predicted by the VTST theory. (C) 2001 John
