2009年3月1日 · The observed lines in the EPR spectra have been attributed to the species of S 2 O −, SO 2-, S 2 O 2-, SO 3-and S 2 O 3-. Each radical has shown two magnetically distinct sites in monoclinic lattice. The angular variation of EPR spectra has also shown that both S 2 O − and S 2 O 2-radicals have two

2024年12月25日 · 电子顺磁共振 (epr) 光谱法阐明退火气氛对改变不同 in 2 o 3 样品中氧空位含量（或数量）的影响，其依据是催化剂中的表面氧空位可以捕获单个电子。

A number of species directly related to the function of the material are characterized using electron paramagnetic resonance (EPR) spectroscopy. Isolated Eu 2+ sites are identified and associated with the substitutional doping for Ca 2+ in the lattice which are responsible for the 645 nm emission of interest.

The radical ions SO4− and S2O3−, trapped in γ‐irradiated K2SO4 and Na2S2O3·5H2O crystals, respectively, have been identified by their ESR spectra. In the preceding paper molecular orbital calculations were described the results of which predict a ···1t163t262a1, 2A1 (symmetry Td) configuration for SO4− and a ···5e45a1, 2A1 ...

The redox properties of the [Fe2(μ-S2O3)2(NO)4]2–anion in CH3CN and CH2Cl2solutions were studied. An addition of excess reducer (sodium thiosulfate) to the thiosulfate complex was shown to produce an EPR signal with g= 2.03 typical of the mononuclear iron dinitrosyl complexes.

2024年12月30日 · 电子顺磁共振 （Electron Paramagnetic Resonance，EPR）是由不配对电子的磁矩发源的一种磁共振技术，可用于定性和定量检测物质原子或分子中所含的不配对电子，并探索其周围环境的结构特性。对自由基而言，轨道磁矩几乎不起作用，总磁矩的绝大部分（99%以 …

2013年12月1日 · The remarkably simple single-line EPR spectrum with a relatively small line width, due to radiation induced cleavage of the S–S bond of the S 2 O 6 2 − ion, is of advantage also in the determination of dose distributions and LET dependence, while such studies are difficult with alanine due to its broad multiline EPR spectrum (Anton and ...

1976年1月1日 · Oxalates and thiosulfates turned out to be very good examples for studying the properties of radicals such as CO, CO', CO2, C04, O03- (oxalates)'-3 or SO2, SO3 (thiosulfates and sulfites)4'5 and hence for in- vestigating extensive decomposition mechanisms of …

电子顺磁共振 (EPR) 作为一种原位技术在高达 1000°C 的高温下应用于离子和混合导体的缺陷化学和传输研究。对于模型材料 Y2O3 稳定的 ZrO2 和 Fe 掺杂的 SrTiO3，平衡吸收强度作为氧分压温度和掺杂含量的函数进行了检查。

The radical ions SO4− and S2O3−, trapped in γ‐irradiated K2SO4 and Na2S2O3·5H2O crystals, respectively, have been identified by their ESR spectra. In the preced
