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%.

The fractions Θβ and ΘX of spin-correlated singlet radical-ion pairs in alkane solutions irradiated by β-particles and X-rays were got from experiments on magnetic field effects and quantum beats in recombination fluorescence.

The fractions Θβ and ΘX of spin-correlated singlet radical-ion pairs in alkane solutions irradiated by β-particles and X-rays were got from experiments on magnetic field effects and quantum beats in recombination fluorescence. The ratio Θβ/ΘX values of 1.3−2.8 for the solvent series studied were found both from magnetic effect and quantum beats. The Monte Carlo calculations were made to explain the variations of Θβ/ΘX in different solvents. The high value of Θβ/ΘX = 2.8 for isooctane is probably due both to large separation between ions in pair and to high concentration of neutral radical in the spur.
