The Reactions of the Nitrogen Atom with Ethylene and Ethylene-d4

Abstract
In the N–C2H4 system, the main final product was HCN, and the stoichiometry (ΔN/HCN) of the reaction was about 1.3. In the N–C2D4 system, CD2 and CD2N were found as the reactive intermediates. We suggested a mechanism different from that proposed by Herron.
