## Abstract During UV.βirradiation of aliphatic carboxylic acids and esters in aqueous and nonaqueous solutions various alkyl and acyl type radicals derived from parent compounds and solvents have been observed by ESR.βspectroscopy. The structures of the radicals point to Ξ±βcleavage, Ξ²βdehalogenati
