Beetwen 1.2K and 4.2K in the metallic state of relaxed (TMTSF)2 CL04, the tunneling of methyl groups gives a central line and four symmetrical satellites in proton N.M.R. In quenched (TMTSF)2CL04 and (TMTSF)2PF6 new satellites give the orientation and amplitude of the local fields (15 G in CL04 and 27 G in PF6) corresponding to an S.D.W. amplitude of 137. and 25% respectively. The S.D.W. seems incommensurate to the lattice.
