Magnetic Interaction in Solvent-free DPPH and DPPH–Solvent Complexes [PDF]
Abstract Magnetic interaction in solvent-free DPPH and DPPH–solvent complexes has been studied by means of measurements of the magnetic susceptibility, the proton magnetic resonance, and the low-field ESR at very low temperatures. The susceptibility of solvent-free DPPH shows a round maximum at 11 K, and then it decreases with a lowering
