The report presents the results of investigations of the mechanism of formation of ionic clusters of ammonia and water molecules, which can react with acid vapor to form condensation nuclei. An apparatus designed especially for the study of near-atmospheric pressure ion-molecule reactions is described. Ionic species that react with the acid to form the condensation nuclei are presumed to be of the type HNH3H2O. These ionic clusters are the products of a series of ion-molecule reactions originating in a corona discharge. The formation of the clusters in moist air containing trace amounts of ammonia is proposed to proceed by the successive formation of N2 initial ion formed in the discharge, N2H and H2O, H3O, HH2O2, . . . , H H2On, and HNH3H2On. A similar mechanism is proposed with O2 acting as the initial ion. Author
