The investigation of the isotopic ratio of interstellar nitrogen -- 14N versus 15N -- is done, for explaining its variations observed for N2H+ in different interstellar and Solar environments. The goal is to produce cross sections and rate coefficients for electron impact dissociative recombination for different isotopologues of N2H+, since it was envisioned as a novel source that can lead to nitrogen fractionation.
