场强增强,穆斯堡尔谱为什么会裂分?The lack ofmagnetic splitting in the 4.2 K spectrum suggests that diamagnetic or integer spin Fe sites are present in the cluster.the isomer shift and quadrupole splitting determined by simulation of the spectra (Table 3) are indicative of LS FeII ions. Spectra collected at the same temperature in an applied magnetic field of 8 T confirmed the diamagnetism of the Fe sites (Figure 2B). This result indicates unambiguously that at 4.2 K the cluster core of 5 is .查看更多
