Reactions of NH+n and ND+n (n = 0–4) with C2H4 and C2D4 at 300 K

Rate coefficients and product-ion distributions for NH⁺_n and ND⁺_n (n = 0–4) with both C₂H₄ and C₂D₄ are presented. The use of the deuterated species allowed the fraction of each of the product ion types to be determined unambiguously. The data also demonstrate how the technique can be used to obtain information on the mechanisms of relatively complex ion/molecule reactions.
