Abstract
Computer solutions to 24 time‐rate‐of‐change equations have been obtained for airlike discharges attainable in a laboratory facility designed for the study of reactions of ionospheric importance. The manner in which the solutions are affected by initial number densities of CO2, NO, NO2, and N2O corresponding to impurity levels of 0, 0.1, 10, and 1000 ppm is presented. The effects of principal reactions on the number densities of detectable species are discussed. For the conditions specified in the computer program, the initial NO density greatly affects the negative‐ion densities, and the initial NO density greatly affects the observable positive‐ion densities.
