Transient absorption spectroscopy of high-mobility ions in decalin
- Argonne National Lab., IL (United States)
Transient absorption spectroscopy is used to demonstrate that pulse radiolysis of a decalin mixture (63% cis-decalin + 37% trans-decalin) with 15 MeV electrons results in formation of high-mobility solvent holes. These radical cations react with perylene with a rate constant of 8.5 x 10{sup 10} mol{sup -1} dm{sup 3} s{sup -1}. This scavenging is faster by an order of magnitude than ion-molecule reactions of normally diffusing ions (nearly (5-7.5) x 10{sup 9} mol{sup -1} dm{sup 3} s{sup -1}). Under conditions of the experiment, the lifetime of the rapidly migrating solvent holes is nearly 150 ns, which identifies them as the high-mobility cations observed by dc and microwave conductivity. 19 refs., 2 figs., 1 tab.
