On the basis of the N3 and N- 3molecular geometries optimized at the B3P86/6 311+ G-level,six different coupling mechanism have been determined for the N3+ N- 3electron transfer system in the ground state,the corresponding geometrical properties,activation energy,stabilization energy,the coupling matrix elements and the density of the electronic state also have been predicted for the various coupling encounter complexes,the electron transfer rates have been calculated by using the Golden-rule scheme,the effect of the coupling pathways on the electron transfer rate has been discussed.
