Kinetics of Cations with C2 Hydrofluorocarbon Radicals

Abstract: Reactions of the cations Ar, O, CO, and CF with the C radicals CH, HCF, CF, and CF were investigated using the variable electron and neutral density attachment mass spectrometry technique in a flowing afterglow-Langmuir probe apparatus at room temperature. Rate coefficients for observed product channels for these 16 reactions are reported as well as rate coefficients and product branching fractions for the 16 reactions of the same cations with each of the stable neutrals used as radical precursors (the species… Show more

“…A number of studies involving the reactions of small cations with radicals including N, O, C 2 H 5 , H 2 C 2 F 3 , C 2 F 3 , and C 2 F 5 have been undertaken using flow-based methods. 129,130 While these studies again primarily focused on establishing rate coefficients, some interesting trends in reactivity were identified. For example, the probability of long-range charge transfer was found to be lower in several ion-radical reaction systems than in the corresponding reactions of ions with closed-shell counterparts.…”

“…Even with the considerable potential for increasing our understanding of gas-phase chemical reactions, experimental studies of ion-radical reactions are extremely rare [14][15][16]. This is because laboratory measurements of ion-radical reactions have been notoriously challenging to make, due to the difficulty of creating dense, pure samples of these reactants.…”
