Summary and Applications of Cluster Ion Reactions Measured at the Ballistic Research Laboratories.
Abstract
Rate constants for room temperature reactions involving atmospheric cluster ions have been measured using two laboratory facilities: A stationary afterglow facility employing photoionization and separate mass analysis for ions and neutrals; and A drift tube facility employing thermionic emission of alkali ions and mass analysis of ions. In the afterglow facility, the sequence of reactions initiated by NO(+) ions reacting in a gaseous mixture of nitric oxide and water vapor and terminated by H2O(+).4H2O has been studied at 296K with each rate constant measured independently. Likewise, the sequence of reactions initiated by NO(+) ions reacting in a gaseous mixture of nitric oxide and ammonia and terminated by NH4(+).3NH3 has been studied at 296K. In the drift tube facility, the clustering of atmospheric gases to the alkali ions Li(+), Na(+), and K(+) has been studied. From laboratory studies of the clustering of atmospheric gases to alkali ions, a map of the minimum values for initial clustering reaction rate constants and equilibrium constants has been drawn. The importance of the formation of a weakly bound cluster ion followed by a switching reaction to form a strongly bound cluster ion to the ion chemistry of the D region has been shown. (Author)
