## Abstract Solution and powder ESR spectra of the 4โtrifluoromethylโ1,2,3,5โdithiadiazolyl and 4โpentafluorophenylโ1,2,3,5โdithiadiazolyl free radicals were analysed. Comparison of the ESR parameters with those obtained for the protonated equivalents shows that fluorination produces a drift of unp
