Mass-Spectrometric Detection of the Ion (SrOK)+


IN a study of the ionization produced by traces of alkali and alkaline earth elements in hydrogen/air flame gases, Wheeler1 has found evidence for ions of the type (BOA)+, where A represents an atom of alkali metal and B one of alkaline earth. Theoretical calculations, by the method of Rittner2, suggest that such ions should be of high stability in the gas phase, the heat of dissociation into BO and A + being of the order of 100 A mixed ion of this type was suggested by the highly specific behaviour given by various A/B pairs. The basic measurements were, however, of electron concentrations, the existence of this particular positive ion being inferred from them, and it seemed desirable to have independent and more direct evidence for their presence.
