The possibility of nitrogen isotopic fractionation owing to ion-molecule exchange reactions involving the most abundant N-containing species in dense interstellar clouds has been explored. We find that exchange reactions between N atoms and N-containing ions have most influence on the fractionation, although the extent of fractionation is too small to be readily detectable.
