| Abstract: | The action of a pulse of elastic waves on polycrystalline mixtures of donors and acceptors (for example, 3,6-di-tert-butylcatechol and 3,6-di-tert-butyl-1,2-benzoquinone with the addition of sulfur and polystyrene) results in the formation of monoradicals and radical pairs. The study of the products by ESR spectroscopy and X-ray analysis shows that the solid powder is dispersed to submicroscopic particles, including those of the mixed composition.Translated fromIzvestiya Akademii Nauk.
