In this review, mechanically detected electron spin resonance (MDESR) in the terahertz (THz) region is described to demonstrate its usability as a novel methodology for obtaining microscopic insights into local electronic structures. Using micromechanical devices, the sensitivity to a small-volume sample is greatly enhanced even for a cavityless setup. Moreover, there are plenty of options in the setup of MDESR, including detection modes, mechanical devices, and detection techniques. ESR spectroscopy of single-crystalline, powder, and frozen solution samples in the THz region are demonstrated.

机械检测的太赫兹电子自旋共振

在这篇综述中，描述了在太赫兹（THz）区域中机械检测到的电子自旋共振（MDESR），以证明其作为获取局部电子结构的微观见解的新颖方法的可用性。使用微机械设备，即使对于无腔设置，对小体积样品的灵敏度也大大提高。此外，MDESR的设置中有很多选项，包括检测模式，机械设备和检测技术。演示了太赫兹区域中单晶，粉末和冷冻溶液样品的ESR光谱。
