The rate constants for the reaction of N4+ with O2, CO2, H2, and D2 have been studied as a function of mean relative kinetic energy in a flow-drift tube using a nitrogen buffer gas. The N2+/N4+ equilibrium, which would otherwise deleteriously effect such a study, was suppressed by adding a trace of H2 as a purge gas that preferentially reacted with N2+. The reaction rates of N 4+ with CO2 and O2 are found to be fast and independent of energy from 0.04 to 0.16 eV. The reactions of N 4+ with H2 and D2, however, have very small rates at room temperature, but the rates increase dramatically with increasing energy, an effect that is attributed to a sensitivity of the reactions to N4++ vibrational excitation. The reaction of N4+ with H2 was studied as a function of temperature and an activation energy obtained. The mobility of N4+ in N2 was extended to higher E/N values than could be done in earlier studies since the effects of the N 2+/N4+ equilibrium were suppressed in the present investigation.
