Effect of proton acceptors on the condensed phase radiolysis of cyclohexane-d12 in cyclopentane

C2H5OH decreases the HD and D2 yields from small concentrations of c-C6D12 in c-C5H10. The results are consistent with a previous suggestion that the enhanced yields in this system are due to exothermic charge transfer. Charge transfer to c-C6D12 is only ~ 10% as efficient as proton transfer to C2H5OH at 4.1 mole % c-C6D12 or C2H5OH. Experiments at 196 and 77 °K suggest that resonance charge transfer in the cyclopentane matrix may occur to some extent.
