我们通过X射线散射散射报告了晶格的电荷转移令人兴奋的字符串，这是一维的自我捕获的多种激发剂。物理参数均由X射线和饮食测量驱动。
We report first direct evidence, by X-ray diffuse scattering, of lattice-relaxed charge transfer exciton strings, which are one-dimensional self-trapped multiadjacent excitons. These non-linear excitations are key objects in quasi–one-dimensional organic compounds that undergo the neutral-ionic transition and are responsible for their physical properties. The one-dimensional fluctuations are very well described within the framework of the transfer integral method and physical parameters are deduced from both X-ray and dielectric measurements.
