✦ Synopsis

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, (7 2 4) X 10" hi-'.szc-' in the case of cyclohexane, for the reaction of solvent positive ions with the solute which are more than tenfold greater than cxpetted for the reaction of molecular positive ions. In the other solvenb, howcvcr, rate constanls on the order of 10" &I-'s-&l are found.
