Visualization of a Discrete Solid-State Process with Steady-State X-ray Diffraction: Observation of Hopping of Sulfur Atoms in Single Crystals of Realgar

A molecular movie showing migration of a sulfur atom between molecules of realgar (α-As4S4) was obtained by a series of structure determinations of the dark stage of this all-solid autocatalytic reaction set.

本研究通过对该全固态自催化反应体系暗阶段的一系列结构测定，成功获取了可展示硫原子在雄黄（realgar，α-As4S4）分子间迁移行为的分子电影。
