Abstract
Proton nuclear relaxation measurements have been performed as a function of the frequency in selectively deuterated NMP TCNQ compounds. The results show that the main source of nuclear relaxation is provided by localized electronic spins, associated with back charge transfer on the NMP stacks. Once their contribution to the relaxation has been subtracted, it appears that the spin dynamics in the TCNQ stacks has a one-dimensional diffusive behaviour, as in other TCNQ conducting compounds.Keywords
