EPR study of γ-irradiated three-furancarboxylic acid

Abstract

The electron paramagnetic resonance of γ -irradiated single crystals of three-furancarboxylic acid has been studied for different orientations of the crystals in a magnetic field. The radicals produced by γ -irradiation have been investigated between 123 and 350 K. The spectra were found to be temperature dependent, and radiation damage centers were attributed to theradical. The principal values of the g-tensor were determined. The results were found to be in good agreement with the existing literature data and theoretical predictions.

Identification of radical structures on 1-pentamethylbenzyl-3-ethylimidazoliumsilver(I)bromide and 1,3-bis(pentamethylbenzyl)-4,5-dimethylbenzimidazoliumsilver(I)bromide exposed to gamma rays: an EPR study

“…In recent years, electron paramagnetic resonance (EPR) technique has been widely used for characterization of various materials . Researchers have investigated compounds containing Ag and Br by using EPR method.…”

Analysis of Poly(2-Hydroxyethyl~Methacrylate)-co- Poly(4-Vinyl Pyridine) Copolymers [COP2,4] Irradiated: an EPR study

“…Sometimes irradiation results in bond scission, degradation of polymer structures [11] and eventually trapped radicals may occur [12]. EPR is a powerful spectroscopic method for detecting radicals in the materials [13][14][15].…”

Comparative Study of Influences of Gamma Rays on Calix[4]Arene and 25,27-di(4-Nitrobenzyl)-26,28-Dihydroxycalix[4]Arene: EPR Study

“…Therefore, it is important to identify radical structures produced by irradiation. EPR is a powerful spectroscopic method for detecting radicals in the materials [7][8][9][10][11][12][13][14][15][16][17][18]. In this study, Calix [4]arene, labeled calix [4]arene (1), and 25,27-di(4-nitrobenzyl)-26,28-dihydroxycalix [4]arene, labeled calix [4]arene(2), were exposed to gamma rays and then radical structures of these calix [4]arenes were evaluated by EPR method.…”
