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., H3OH2On NO3-HNO3m. 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 cmsec 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 1T, 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
