Reaction with atomic nitrogen

Similarly, the reaction with atomic nitrogen produces NHj, NH2 and NH ... 

The rates of these reactions also depend on the abundance of CN, a molecule significantly destroyed by the neutral-neutral reaction with atomic nitrogen. The...

The reaction with most nitrogen nucleophiles gives the substitution products in adequate yields.Apparent exceptions are the )8-lactam reactions, but considering the low nucleophilicity of the amide nitrogen atom and the geometrical constraints imposed on the reaction, the yield is surprisingly high. 

Fastrup et al. [9] presented a detailed experimental study of the hydrogenation of an iron-based surface precovered with atomic nitrogen using the temperature-programmed surface reaction (TPSR) method. Their modeling results clearly demonstrate the effect of the initial coverage of N- and the effect of the H2 partial pressure. The kinetic mechanism of the TPSR experiment can be written as depicted below.

Tree, 1987). Concerning the problem of interstellar ammonia formation, the low temperature measurements demonstrate that the reaction of atomic nitrogen ion with hydrogen is not an efficient route. Therefore it is still a problem to explain ammonia abundance in interstellar clouds.
