Binary Positive Ion-Negative Ion Mutual Neutralization Reactions.
Abstract
The results are described of a study of the rate coefficients at thermal energies of several binary positive ion-negative ion mutual neutralization reactions. This includes reactions of the simpler molecular ions e.g., NO(+) + NO2(-) and those of the so-called cluster ions e.g., H3O(+)(H2O)n + NO3(-)(HNO3)m. The ionic recombination coefficients alpha for all of these molecular ion reactions are similar being within the range (4 to 10) times 10 to the -8th power cu cm/sec in general accordance with theoretical predictions. The variation with temperature of two simple ion reactions have also been obtained and alpha varies as sq rt of (1/T), again in line with the theory. For several atomic ion reactions e.g., AR(+) + Cl(-), alpha is much smaller than for reactions involving molecular ions. A spectroscopic study of one reaction (NO(+) + NO2(-)) has been carried out and data on the product neutral states have been obtained. (Author)
