The observed species in glycyl- L- glutamine monohydrate powders were attributed to the CH2<(C)over dot>NHCOOH radical; and those in iminodiacetic acid and methyliminodiacetic acid powders to the HN<(C)over dot>HCH2(COOH)(2) and H3CN<(C)over dot>HCH2(COOH)(2) radicals respectively. The spectra were computer simulated and the g values of the radicals and the hyperfine structure constants of the unpaired electron with nearby protons and N-14 nucleus were determined. The results were found to be in good agreement with the existing literature data.eninfo:eu-repo/semantics/closedAccessEprFree RadicalsGamma IrradiationAmino AcidIminodiacetic Acid DerivativesArticle16314753WOS:0002518378000072-s2.0-3754901034510.1080/10420150701464343Q3Q4
