In these compounds, the observed paramagnetic species were attributed to the HOOCCH2CH2CH2CHCOOH and CH2COONH4 radicals, respectively. The g values and the hyperfine coupling constants of the unpaired electron with the environmental protons were determined for these two radicals. In work, the observed paramagnetic species were found to be stable at room temperature for more than two months. Also, these compounds were characterised by FT-IR and UV-VIS. Their thermal stabilities were determined by TGA and DTA measurements. Thermal analyses were shown to be unstable of the HOOCCH2CH2CH2CH(NH2)COOH and CH3COONH4 against thermo-oxidative decomposition.eninfo:eu-repo/semantics/closedAccessAmmonium AcetateDl-2-Aminoadipic AcidFt-IrFree RadicalsEprArticle1693256264WOS:0003319290000092-s2.0-8489765476710.1080/10420150.2013.860977Q3Q4
