โฆ Synopsis
A very high field EPR spectrometer, which can operate at magnetic fields up to I9 T, has been constructed. The first EPR spectra of a nitroxide free radical in solution are reported. A discussion of the applications of high frequency EPR (corresponding to the far infrared) is presented.

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.
