The structures and stabilization of six nitrogen-centered radicals NHCH=CHR(R=H 、 BH2、 CN、 F、 OH、 NH2) have been studied with ab initio method at UHF/4-31G level, full optimized. The energies of stabilization of six radicals NHCH=CHR(R=H、 BH2、 CN、 F、 OH、 NH2) are 0.00、-34.92、-8.35、-0.93、33.05、50.85kJmol-1) respectively, which indicated that the substituents OH and NH2 play a role of stabilization on the nitrogen-centered radical and BH2 、CN play a role of de- stabilization.

Key words: Nitrogen radical, ab initio calculation, Stabilization energy
