NMR study of the anionic motion in the (TMTSF) 2PF 6 organic conductor

Abstract

The 19F nuclear magnetic resonance spin-lattice relaxation in an organic superconductor, (TMTSF) 2PF 6, was investigated in view of the molecular motions of the anionic sublattice structure. The temperature dependence of the spin-lattice relaxation was described well by the anionic molecular motions in unequal potential wells with distinct activation energies and correlation times.
