Fig. 3


Nitrogen isotopologue ratios (as labeled) in the doubly substituted species, as well as the singly substituted diazenylium and molecular nitrogen, as predicted when including the fractionating reactions of Table 3 (solid) and not including them (dashed). The red graphs represent 15NN/15N2, the orange N15NH+/15N2H+, the purple 15NNH+/15N2H+, the yellow N2H+/15NNH+, the blue N2H+/N15NH+, and the green N2/N15N.
