Products of Ionization by Electron Impact in Methyl and Ethyl Alcohol

Abstract
Fourteen different ions were observed in methyl alcohol and twenty-five in ethyl alcohol. The appearance potentials of many of these were measured and the manner of dissociation in several cases was definitely established. The ionization potentials of the two molecules were found to be 10.8 volts for methyl and 11.3 volts for ethyl alcohol. In all cases subject to unambiguous interpretation that reaction occurred which required the least dissociation energy. The concept of localized charge on the oxygen atom in certain complex ions is supported by the results.
