Abstract
Rate coefficients and product branching fractions have been determined for 31 ion-molecule reactions involving PF5 or PF5-. About half of th e reactions studied show an ion-molecule association channel. NH2- and OH- reaction with PF5 yields HF product. F- and electron transfer cha nnels are also observed in many of the reactions studied. Consideratio n of the efficiency of the electron transfer channel in these reaction s leads to the conclusion that the adiabatic electron affinity of PF5 is 0.75 +/- 0.15 eV.
