The phase shift of quantum oscillations observed in the recombination fluorescence of the (diphenylsulfide-d10)+/(p-terphenyl-d14)− radical ion pair in isooctane has been detected experimentally. The shift is caused by the delay in (diphenylsulfide-d10)+ formation in the reaction of solvent holes wi...
The phase shift of quantum oscillations observed in the recombination fluorescence of the (diphenylsulfide-d10)+/(p-terphenyl-d14)− radical ion pair in isooctane has been detected experimentally. The shift is caused by the delay in (diphenylsulfide-d10)+ formation in the reaction of solvent holes with a diphenylsulfide molecule. Comparison with a theoretical model has given for the rate constant of isooctane hole capture by diphenylsulfide molecules the value (3.5±1) × 1010M−1s−1 which exceeds the diffusion-controlled one. The fraction of singlet-correlated pairs in the track has been estimated from the oscillation amplitude to be approximately 35%.

Amplitudes of quantum oscillations observed in the recombination fluorescence of the (diphenylsulfide-d10)+/(p-terphenyll-d14)− radical ion pairs in alkane solutions have been used to estimate a fraction of spin-correlated singlet pairs Θ in the radiation track.

Amplitudes of quantum oscillations observed in the recombination fluorescence of the (diphenylsulfide-d10)+/(p-terphenyll-d14)− radical ion pairs in alkane solutions have been used to estimate a fraction of spin-correlated singlet pairs Θ in the radiation track. Θ values of 0.36 – 0.54 for the solvent series studied were found. Values for a fraction of singlet recombinations fs (0.52–0.66), calculated from Θ values, are in satisfactory agreement with those available from literature. It has been observed that Θ and fs values decrease with increasing solvent viscosity (from n-hexane to cis-decalin).
