Abstract : kPs values are an indication of o-Ps reactivity in molecular media via pseudo first order kinetics. Although pure pentene isomers exhibit similar o-Ps annihilation characteristics, cis-2-pentene shows rather unusual behavior when mixed with abs. EtOH and a heavy metal catalyst. In this study, comparison of kPs values in pure 1-pentene, trans-2-pentene and cis-2-pentene isomers with those for various abs. EtOH-pentene isomers-Pt, abs. EtOH-pentene isomer-Pt-on-charcoal and D2O-Pd mixtures will serve to further characterize o-Ps behavior in molecular liquids. The kPs values will also be indirectly related to catalytic activity of Pt and Pt-on-charcoal.
