The relative yields of cyclohexyl radical in pulse-irradiated liquid cyclohexane and cyclohexane solutions containing negatwe (C02) and positive charge scavengers (cis-and trans-decalin) are measured via time-resolved EPR. Charge scavenging has a negligible effect on radical production. A mechanism

β¦ Synopsis
Previous experimental observations and new pulse ndiolyds results concemmg the high-mobfity positive ion in cycloh-e are examined_ Apparent dir;agzrcernent among these observations concerning the existence of a high-mobility positive ion can be explained If there are two positive ions of major importance m cyclohexane radiolyti. l3e possibility is examined that the cCsH:z ion has a "normal" mobility and that hydride tisfcr or proton tisfer, involving c-C~H:~ or cCeHf3 respectively, is responsible for the observed h&h mobility_

The formation kinetics of the ions ThlPD+ and pyrene+ have been studied in pulse irradiated dilute solutions of TMPD and pyrene in cyclopentane, n-hexane, cyclohexane, methylcyclohexnnc. iso-octane and cycle-octane. In cyclohexane and methylcyclohexane the rates of formation indicate rate constants,
