Abstract
IN a recent paper1 I put forward the hypothesis that active nitrogen is simply the positive ions of the nitrogen molecule, N2 + (X') produced in the discharge tube. It was suggested that the excitation of the First Positive Bands—the characteristic active nitrogen spectrum—is due to the neutralization of N2+ by a three-body collision, with the neutral N2 molecule as the third body, in the volume rather than on the surface of the discharge vessel.
