Abstract
The geometries,energetics and spectroscopic properties of the coordination clusters of NxHy-Fe(x=0~2,y=0~3) were investigated using B3LYP/6-311G** method.The mechanism of hydrogenation of nitrogen into ammonia was discussed on the pure iron surface.It was suggested that the ammonia synthesis may pass away via N2 and N2H2 species.Also,the calculated frequencies are in good agreement with the experiments.
