a Isotopologues of the ammonium cation (15N\({{{{{{\rm{D}}}}}}}_{x}{{{{{{\rm{H}}}}}}}_{4-x}^{+}\)) are present in the aqueous solution. The fraction of deuterium was varied by changing the amount of H2O vs. D2O. Isotopologues are labeled xD where x represents a number of deuterium atoms in the molecule. b Equilibrium molar fractions of the isotopologues as a function of deuterium fraction in solution as determined by Eq. (1).
