The structures and stabilization of nine nitrogen-centered radicals have been studied with ab initio method at UHF/4-31G level, full optimized. The energies of stabilization of nine radicals NHR (R=CH3, CF3, CCl3, CN, NH2 , CHO, OH, COOH, F) are 25.24, -38.53, -20.59, 21 .46, 19. 96, 58.82, 73.69, 31.75, 63.85kJ•mol-1, respectively, which indicated that except CF3 and CCl3, other seven substituents play a role of stabilization on the nitrogen-centered radical.

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