Abstract: | Rate coefficients for the association reactions of NO+ ions with N2 and CO2, O2+ with N2, and N+ and N2+ with N2 have been determined as a function of gas temperature in a laboratory experiment employing a variable-temperature drift-tube apparatus. The measured rate coefficients were fitted to power laws of the form where the exponents x ranged from 2.2 to 4.3. The strong temperature dependence observed in the case of the reaction of NO+ with N2 (x = 4.3) supports the thesis by Arnold et al. (1979) that the temperature variability of D-region ion densities is a result of this reaction step in the ion clustering sequence. |
