Abstract
In this paper we collect and detail recent results concerning ⁷⁷Se and ¹³C nuclear relaxation rate measurements obtained on several representatives of the (TMTSF) ₂X and (TMTTF) ₂X series of charge transfer salts as a function of temperature and hydrostatic pressure. From the temperature and pressure dependences of T^-1₁, for the compounds (TMTTF) ₂PF ₆, (TMTTF) ₂Br, (TMTSF) ₂PF ₆ and (TMTSF) ₂ClO ₄, we are in a position to extract the nature, the amplitude, the statics, the dynamics and finally the dimensionality of spin correlations that characterize the unified phase diagram of both series of materials.
