First time-resolved EPR observation of Nafion photochemistry.
Time-resolved EPR spectra of UV-irradiated Nafion reveal the formation of spin-polarized excited triplet states and allow the detection of photoinduced triplet-triplet energy transfer processes through hydrogen bonds between water and sulfonic acid groups.
