Resumé

The resonance position and spin-lattice relaxation rate of well-resolved C13 sites of the tetramethyltetraselenafulvalene (TMTSF) molecule in the organic conductors (TMTSF)2ClO4, (TMTSF)2ReO4, and (TMTSF)2PF6 have been measured as a function of temperature between 340 and 220 K. Comparison with neutral TMTSF and the use of Korringas law has permitted determination of the electronic contribution to the relaxation rate and the resonance position. A change in slope in the resonance position as a function of temperature is an indication of a possible redistribution of the spin density over the molecule.
