CONSECUTIVE ION-MOLECULE REACTIONS IN METHANE INVESTIGATED BY MEANS OF POSITIVE ION-IMPACT,

Abstract

The ion-molecule reactions in methane (CH4) were studied in detail up to third order processes in the pressure range 0.00008 - 0.001 mm Hg. From the pressure dependence of the ion currents, the mechanism of the formation of the product ions can be determined as a function of the energy absorbed by the molecule during the charge exchange. The ion-molecule reactions are discussed. Between 15.5 eV and about 20 eV the fragment ion CH2(+) is formed in the ground state, but above 20 eV the main part of the CH2(+) ions is probably in an excited state that can cause ion-molecule reactions of different type.
