Abstract
Electron spin-lattice, T 1, and spin-spin, T 2, relaxation times in polyacetylene samples have been measured by a saturation method at 2 mm waveband EPR at 90–330 K. Temperature dependences of the intrachain diffusion and interchain hopping rates in trans-(CH) x are evaluated. Spin dynamics in pristine trans-(CH) x does not agree with the predictions of the soliton model, but it is in a good agreement with the intersoliton isoenergetic electron hopping model of charge transport predicted by Kivelson.
