DISSOCIATION OF ETHANOL MOLECULE IONS FORMED IN CHARGE EXCHANGE COLLISIONS WITH POSITIVE IONS
Mass spectra of C/sub 2/H/sub 5/OH were obtained after charge exchange with slow positive ions. The intensities of the peaks were plotted as a function of the energy absorbed by the molecule during the charge exchange. Integration of these curves gives a mass spectrum in good agreement with that obtained in electron impact. Further, the graph gives experimental information about the dissociation processes in a large molecule ion. Comparison with the corresponding graphs obtained by means of the statistical theory of mass spectra shows disagreement in several respects. The dissociation processes were therefore interpreted without use of this theory. The low intensity of ions formed by loss of H/sub 2/O and CH/sub 4/ shows that in an electron impact experiment these ions are formed from a highly excited neutral molecule. (auth)
