Studies of reactions of C 3H + ions in the gas phase at 296±2 K

Abstract

Rate constants and product distributions have been determined for ion-molecule reactions between C 3H + and H 2, D 2, CO, N 2, O 2, CO 2, OCS, H 2O, H 2S, CH 3OH, NO, N 2O, NH 3, ND 3, CH4, HCN, CH 3CN, C 2N 2, C 2H 2, C 2D 2 and C 2H 4. The measurements were done using the Selected-Ion Flow Tube or SIFT technique at 296± 2 K. The observed reactions exhibit a wide range in reactivity and a large variety of pathways including proton transfer, charge transfer, hydride abstraction, complex formation and association. Many of these reactions provide routes for CH, CC, CO, CN or CS bond formation in the ion and/or neutral product which are of relevance in molecular synthesis by ion chemistry.
