Abstract
High-field/high frequency EPR spectroscopy measurements are shown. Experime nts were carried out at 240- and 316-GHz frequencies. The employed apparatu s uses a novel combination of far infrared molecular lasers and of probehea d 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 spec troscopy up to the THz regime.
