摘要：

We present C-13 NMR lineshapes and spin lattice relaxation measurements of (TMTTF)2Br and (TMTSF)2PF6 in the spin density wave (SDW) state. We confirm that (TMTSF)2PF6 has an incommensurate SDW and show that the phason mode is dominant in the relaxation. We prove that (TMTTF)2Br is commensurate and estimate the SDW amplitude. No phason contribution to the relaxation is observed in this compound. The implications for theory are discussed.
