## 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
The room temperature gamma irradiation degradation of the lithographic polymers, poly(methylmethacrylate) (PMMA), poly(methy1-a-chloroacrylate) (PMCA), poly(methy1-a-fluoroacrylate) (PMFA), and poly(methylacrylonitri1e) (PMCN), have been studied by electron spin resonance and electron nuclear double
