| Abstract: | Electron spin-lattice relaxation rate Tl?1 has been measured at low frequencies 5–450 MHz in pristine trans-polyacetylene. Frequency dependence of Tl?1 gave dimensionality of diffusive motion of electron spins (neutral soliton). Relaxation mechanism was identified as dipolar and hyperfine origin based on an electron spin concentration dependence of Tl?1. |
