Nuclear Spin-Lattice Relaxation in trans-(CH)x. A Confined Soliton Model Including Nuclear Spin-Flip Diffusion
Trans-polyacetylene is known for quite some time to contain paramagnetic spins as a consequence of a bond-alternating defect. The interpretation and structural analysis of these defects in terms of topological kinks (solitons) by Su, Schrieffer and Heeger  has provided tremendous impetus to this field of research.
