The physical properties of quasi-two-dimensional organic conductors based on bis (ethylenedithio) tetrathiafulvalene (BEDT-TTF) have been extensively studied since the discovery of superconductivity at ambient pressure in ß-(BEDT-TTF) 2I3 1). Measurements of the nuclear spin-lattice relaxation time T can provide a wealth of microscopic information on the electronic spectrum and molecular motion in these systems. In the present work we discuss the results of the proton T1 measurements in (BEDT-TTF) 2X (X = I3, Cu(SCN)2) and (BEDT-TTF)4Z (Z = Hg2.899Br8, Hg2.78Cl8) in the temPerature range 4.5 – 310 K with a special emphasis on the mechanisms of spin relaxation.
