Abstract

High-field/high frequency EPR spectroscopy measurements are shown. Experiments were carried out at 240- and 316-GHz frequencies. The employed apparatus uses a novel combination of far infrared molecular lasers and of probehead exploiting dielectric resonators working in the whispering gallery modes. This approach constitutes a relatively simple method of multifrequency EPR spectroscopy and opens appealing perspectives in high-sensitivity EPR spectroscopy up to the THz regime.

摘要

展示了高场/高频电子顺磁共振光谱测量结果。实验在240 GHz和316 GHz频率下进行。所采用的仪器使用了远红外分子激光器和利用在回音壁模式下工作的介质谐振器的探头的新颖组合。这种方法构成了一种相对简单的多频电子顺磁共振光谱方法，并为高达太赫兹频段的高灵敏度电子顺磁共振光谱开辟了有吸引力的前景。
