Abstract
The ion-molecule reactions in C3H6 and C2H4 systems are studied by Fourier transform ion cyclotron resonance (FT-ICR) spectrometry. The ejection technique is used to elucidate complex ion-molecule reactions in C3H6 and C2H4. All the ions except the specific reactant ions are ejected from the cell so that the reactions of selected ions with the parent gas molecules can be examined. In the C3H6 system two secondary reactions: C3H7++C3H6→C4H9++C2H4 and C4H7++C3H6→C5H9++C2H4 and in the C2H4 system a secondary reaction: C3H5++C2H4→C5H7++H2 are identified and their relative rate constants are determined from measurements of the reactant and product ion intensities as a function of reaction time in the cell.
