The EPR laboratory is equipped by spectrometer Bruker E580 ELEXSYS, designed to measure electron paramagnetic (spin) resonance in both modes - continuous wave (CW) and pulsed (FT), both in the most common X-band (9,4-9 8 GHz) and in Q-band (34 GHz) frequencies. In both frequency ranges spectrometer comprises a system for measuring ENDOR (electron nuclear double resonance) and ELDOR (electron-electron double resonance). The spectrometer is equipped with the cryostat allowing measurements in the range 1.8-300 K. The light excitation of samples can be performed with an optical cryostat system allows using various types of lamps or OPO laser generating ns pulses at wavelength interval 210-2700 nm.
