Dynamic nuclear polarization (DNP) is presented as an applicaformed with insoluble (16) or soluble free radicals (5,6), tion for EPR spectroscopy in low magnetic field (below 40 G). but the most widely used free radicals are nitroxides dis-An updated theory of DNP allows the calculation of the maxim

EPR irradiation by a train of inverting pulses has potential advantages over continuous-wave EPR irradiation in DNP applications; however, it has previously been used only at high field (5 T). This paper presents the design and testing of an apparatus for performing pulsed DNP experiments at 10 mT w

Spin-lock adiabatic field cycling imaging (SLOAFI) relaxometry was shown to be a useful technique for obtaining a fast study of spin-lattice relaxation dispersion in the rotating frame. The aim of the present article is to describe some technical aspects of the experiment in more detail, while showi
