Recombination of Ions in Flames

A technique for measuring recombination rates in flames is described and some results showing the effect of temperature, pressure, and the presence of electronegative gases on recombination are presented. Experimental results are compared with predictions based on present-day theories of recombination. Results are interpreted in terms of an ion—ion process with recombination occurring most probably between an OH— and an H3O+ ion. The importance of electron attachment in such a process is emphasized.
