Abstract

The experimental studies on ultrafast relaxation processes in organic radicals are presented. Three mechanisms of ketyl radical formation are established and separated: direct transfer of a hydrogen atom as a whole; two-stage transfer of an electron and of a proton in an excited complex; and proton transfer at diffusion encounters of anion and cation radicals. The thiyl radicals formation at homolytical photodissociation of organic sulfides by picosecond laser pulses occurs at a rate constant k
