The effect of temperature on EPR linewidth, intensity and spectra was investigated. The room temperature EPR spectra of ionizing radiation-induced timolol were recorded in dimethyl sulfoxide solution at a frozen state. The first-order kinetic mechanism rate constant of timolol was calculated. The findings on all EPR experimental data indicated that ionizing radiation-induced stable-free radical species on timolol are characterized byg= 2.0027.eninfo:eu-repo/semantics/closedAccessEprIonizing radiationTimololKineticsArticle1759-10892897WOS:0005496038000012-s2.0-8508757180210.1080/10420150.2020.1780594Q3Q4
