Descrição: The free radicals formed in solid n-propanol by radiolysis and photolysis were examined by electron paramagnetic resonance (EPR) techniques. Identification of the radicals is based on modifications in the EPR hyperfine (hf) structure introduced by substituting deuterium for hydrogen at selected positions in the molecules. Radiolysis leads to radical formation by removing a hydrogen atom from the alpha carbon while photolysis apparently favors hydrogen abstraction from the beta carbons. While corroborative evidence regarding the hydrogen atoms was obtained from mass spectrographic analyses of the gas liberated during irradiation, the analysis also shows that some hydrogen gas escapes from other than the alpha and beta carbon positions. The experimental EPR hf spectra are compared to a series of constructed spectra obtained by summing gaussian absorption curves according to the interactions indicated by the proposed models of the radicals.
