NMR Studies of Exotic Members of Bechgaard Salt with Non- centrosymmetric Anions under Pressure
The electronic properties of (TMTSF) 2FSO 3 have been investigated under pressure of 0.65 GPa by measuring 77Se-NMR lineshape, spin-lattice relaxation rate ( T 1 − 1 ) and spin-spin relaxation rate ( T 1 − 1 ) measurements on a single crystal sample. The NMR signal was found abnormally broadened bel...
