Pairwise trapping of radicals in γ-irradiated malonic acid single crystals

High dose irradiation of malonic acid single crystals (up to 3 × 10 21 eV/g) leads to the formation of measurable amounts of radical pairs. The build-up curve and the composition of radical pairs strongly suggest that the pairwise trapping is due to occasional overlapping of spurs. The stability of...

Description
Summary:High dose irradiation of malonic acid single crystals (up to 3 × 10 21 eV/g) leads to the formation of measurable amounts of radical pairs. The build-up curve and the composition of radical pairs strongly suggest that the pairwise trapping is due to occasional overlapping of spurs. The stability of the pairs at a given temperature is a function of the distance between the radical sites but also of the relative orientations of the free electron orbitals.
