![]() ![]() Above 200 K the EPR spectrum was mainly due to the CO 2 Upon warming, both the radical pairs and the reduction product decay, the latter apparently by a transient species. – radicals were also observed and the tensor for the electron-electron dipolar coupling was determined for the strongest coupled pair, which exhibited the largest spectral intensity.Hyperfine coupling tensors for proton and lithium interactions were obtained for these two radicals and show that the latter radical exists in four conformations with various degrees of bending at the radical center. – radical and a protonated electron-gain product.Mainly two radicals are present at 6 K, the well-known CO 2 Periodic density functional theory calculations were used to assist in assigning the radical structures. In this study, single crystals were X irradiated at 6−8 K and radical formation at these and higher temperatures were investigated. A material used in EPR dosimetry have been studied using electron paramagnetic resonance (EPR), electron nuclear double resonance (ENDOR) and ENDOR-Induced EPR (EIE) techniques. Radiation-induced primary radicals in lithium formate. ![]()
