Abstract
Temperature dependences of electron spin-lattice relaxation times for cis- and trans-polyacetylene are measured at 2 - 40 K. A model of rela xation in trans-polyacetylene is suggested where the relaxation procee ds via spin diffusion to fast relaxing centers (a pair of close spins, one of which is highly mobile). Theoretical calculations of relaxatio n rates for both configurations of polyacetylene are presented, which give qualitative and quantitative description of measured relaxation t imes.
