Determination of Magnetic and Nuclear Quadrupole Interactions in La@C82 from EPR Linewidth Data

Abstract From the analysis of the temperature dependence of the EPR line width, an estimate of the anisotropic parts of the dipolar and quadrupolar hyperfine couplings of lanthanum was derived. Furthermore, the rotational correlation time of the nearly spherical molecule was found to deviate considerably from that of the solvent molecules.
