Abstract : Mass spectra of ethanes (C2D6, C2H6, and CH3CD3) 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 reasonable agreement with that obtained in electron impact. The most interesting of the ion-molecule reactions observed at low velocity of the incident ion is COH= = C2D6 yields C2D6H= = CO. The way in which the ion formed dissociates indicates that the ionized carbon in this intermediate ion must be considered as having the valency five with all bonds of approximately equal strengths.
