Abstract
Magnetic and dynamics properties of paramagnetic centers in various tr ithiolium cations were characterized by static magnetic susceptibility measurements and EPR spectroscopy. Magnetically correlated units cons isting of at least pairs of spins with ferromagnetic exchange coupling were found in some trithioles. The rates of intramolecular spin diffu sion and intermolecular spin hopping were estimated separately. The ra tes and the anisotropy (nu(parallel to)/nu(perpendicular to) = 20-300) of spin dynamics were shown to depend on the molecular structure.
